matching.<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Not every inquiry needs every field.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But the more requirements that are already known, the easier it is to avoid comparing products that do not match the project.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"system-voltage\">1. Specify the System Voltage<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Start with the voltage defined by the project.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Examples of <a href=\"https:\/\/ritoks.com\/product-category\/ac-power-protection\/\">current published RITOKS AC MCB families<\/a> include products with ratings such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>AC 230\/400V<\/li>\n\n\n<li>AC 240V<\/li>\n\n\n<li>AC 230\/240V<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These are product-family examples, not instructions for choosing a voltage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The buyer should provide the voltage required by the actual electrical system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A good RFQ field is simply:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">System voltage: [required voltage]<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">If the project uses a particular supply arrangement or has additional voltage-related requirements, include those separately.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"rated-current\">2. Provide the Required Current Rating<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The supplier should not have to infer the required breaker current from the application name alone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the project specification already defines the current rating, include it directly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Rated current: [required current]<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">Current RITOKS AC MCB families cover different published ranges, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1\u201332A<\/li>\n\n\n<li>1\u201363A<\/li>\n\n\n<li>6\u201363A<\/li>\n\n\n<li>10\u201363A<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The published range only tells the buyer what a particular family currently offers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It does not determine what current rating the circuit itself requires.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For broader current, pole and curve selection considerations, see the <a href=\"https:\/\/ritoks.com\/ac-mcb-selection-guide\/\">AC MCB Selection Guide<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"pole-configuration\">3. Specify the Pole Configuration<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Pole configuration should be written explicitly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Possible requirements may include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1P<\/li>\n\n\n<li>1P+N<\/li>\n\n\n<li>2P<\/li>\n\n\n<li>3P<\/li>\n\n\n<li>3P+N<\/li>\n\n\n<li>4P<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Different RITOKS product families publish different combinations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, RTSXD01 and RTSXD04 currently list:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1P+N<\/li>\n\n\n<li>2P<\/li>\n\n\n<li>3P<\/li>\n\n\n<li>3P+N<\/li>\n\n\n<li>4P<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">RTS-ACM60 currently lists:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1P<\/li>\n\n\n<li>2P<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The RFQ should therefore state the configuration already required by the project rather than asking for \u201ca breaker\u201d without pole information.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the project specifically depends on neutral switching, neutral protection or another internal pole behavior, include that as a separate documentation requirement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Do not assume the configuration label alone confirms those details.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For more information, see <a href=\"https:\/\/ritoks.com\/1pn-vs-2p-circuit-breaker\/\">1P+N vs 2P Circuit Breakers: Configuration Questions for Buyers<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"trip-curve\">4. Include the Required Trip Curve<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If the project already specifies a trip characteristic, include it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Trip curve: B<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">or:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Trip curve: C<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">or:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Trip curve: D<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">Current published RITOKS data confirms:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>RTSXD01 \u2014 B\/C\/D<\/li>\n\n\n<li>RTSXD03 \u2014 B\/C<\/li>\n\n\n<li>RTSXD02 \u2014 B\/C<\/li>\n\n\n<li>RTSXD04 \u2014 B\/C\/D<\/li>\n\n\n<li>RTS-ACM60 \u2014 B\/C<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">RTS-AC47 does not currently have a confirmed curve designation on its published page.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The RFQ should not ask the supplier to infer the correct curve solely from a simple label such as \u201cmotor,\u201d \u201clighting\u201d or \u201cindustrial panel.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the curve has not yet been defined, that engineering requirement should be resolved separately.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">See <a href=\"https:\/\/ritoks.com\/b-curve-vs-c-curve-vs-d-curve-mcb\/\">B Curve vs C Curve vs D Curve MCBs: What\u2019s the Difference?<\/a> for a focused explanation of trip-curve terminology.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"breaking-capacity\">5. State the Required Breaking Capacity<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Breaking capacity is another specification that should be provided when it has already been established for the project.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A buyer might write:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Breaking capacity: [required kA]<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">Current RITOKS published data includes examples such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>RTSXD01 \u2014 10kA Icn \/ 7.5kA Ics<\/li>\n\n\n<li>RTSXD02 \u2014 6kA<\/li>\n\n\n<li>RTSXD03 \u2014 6kA<\/li>\n\n\n<li>RTSXD04 \u2014 10kA Icn \/ 7.5kA Ics<\/li>\n\n\n<li>RTS-ACM60 \u2014 6kA typical, subject to variant confirmation<\/li>\n\n\n<li>RTS-AC47 \u2014 1kA<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Where a product page publishes only a kA value without identifying Icn or Ics, the missing designation should not be invented.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Likewise, the supplier should not be assumed to determine prospective short-circuit current simply from the RFQ\u2019s voltage and application description.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the project engineering documentation already includes prospective short-circuit current or a required breaking capacity, include it in the inquiry.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For the technical distinction, see <a href=\"https:\/\/ritoks.com\/6ka-vs-10ka-mcb-breaking-capacity\/\">6kA vs 10kA MCB: Understanding Breaking-Capacity Ratings<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"icn-ics\">6. Include Icn or Ics Requirements When They Matter<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Not every sourcing inquiry needs a separate Icn or Ics field.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But when the specification explicitly requires one, write it clearly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Required short-circuit rating designation: [Icn \/ Ics \/ project specification]<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">This matters because some current RITOKS product pages publish both values while others do not.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">RTSXD01 and RTSXD04, for example, currently publish:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>10kA Icn<\/li>\n\n\n<li>7.5kA Ics<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">RTSXD02 and RTSXD03 publish 6kA without a separate Icn\/Ics designation on the current site.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The RFQ should preserve the terminology used by the project rather than treating different short-circuit rating terms as interchangeable.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"mounting-space\">7. Describe Mounting and Space Constraints<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For OEM panel projects, electrical ratings are only part of the sourcing question.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Physical installation can matter as well.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Useful RFQ information may include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>required DIN rail format<\/li>\n\n\n<li>available panel space<\/li>\n\n\n<li>maximum device dimensions<\/li>\n\n\n<li>preferred terminal arrangement<\/li>\n\n\n<li>accessory space<\/li>\n\n\n<li>dimensional drawing requirement<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Several current RITOKS AC MCB families publish 35mm or 35.5mm DIN rail mounting information.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, this should not be treated as a substitute for full dimensional confirmation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If panel space is tight, ask for the exact dimensional drawing for the selected model and configuration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A useful RFQ entry is:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Maximum available space \/ dimensional constraint: [project requirement]<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"accessories\">8. Mention Required Accessories<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Some MCB projects involve more than the base breaker.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Current published product information includes examples such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>RTSXD04 \u2014 optional F3 auxiliary contact and S3 shunt release<\/li>\n\n\n<li>RTS-AC47 \u2014 optional shunt-trip release<\/li>\n\n\n<li>RTS-ACM60 \u2014 optional residual-current module<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If the project needs an accessory, include it explicitly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Required accessory: [auxiliary contact \/ shunt release \/ other specified accessory]<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">Do not assume that an accessory is compatible with every breaker variant.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The breaker and accessory combination should be confirmed together.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For accessories with electrical parameters, such as a shunt-release control voltage, provide the required specification where available.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"documentation\">9. Specify the Required Documentation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For B2B and OEM panel procurement, technical documentation can be as important as the product itself.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Depending on the project, buyers may request:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>datasheet<\/li>\n\n\n<li>dimensional drawing<\/li>\n\n\n<li>connection diagram<\/li>\n\n\n<li>time-current information<\/li>\n\n\n<li>breaking-capacity documentation<\/li>\n\n\n<li>applicable standard information<\/li>\n\n\n<li>certification evidence<\/li>\n\n\n<li>accessory documentation<\/li>\n\n\n<li>product labeling information<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A request for documentation does not mean every document is automatically available for every model.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The better wording is:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Required documentation: [list documents required for approval]<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">The supplier can then confirm what is available for the exact model and variant.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"standards-certification\">10. Separate Standard Requirements From Certification Requirements<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A product page may mention a standard reference.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That is not automatically the same as providing a certificate, laboratory report or approval accepted in a particular market.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If a project requires a specific standard, state:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Required standard: [standard]<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">If it also requires documentary evidence, state that separately:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Required certification \/ evidence: [document or approval requirement]<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">This distinction helps prevent ambiguity during quotation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Do not assume that a standard mentioned on a product page guarantees every required certificate or destination-market approval.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"destination\">11. Include the Destination Country or Market<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For international procurement, destination information can be useful.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It may affect discussions around:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>documentation<\/li>\n\n\n<li>labeling<\/li>\n\n\n<li>packaging<\/li>\n\n\n<li>standard requirements<\/li>\n\n\n<li>commercial terms<\/li>\n\n\n<li>delivery arrangements<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A simple RFQ field is:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Destination market: [country \/ region]<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">This does not mean the supplier automatically guarantees regulatory compliance in that market.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Any market-specific approval requirement should be stated explicitly and verified separately.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"quantity-delivery\">12. Provide Quantity and Delivery Requirements<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Technical specifications are only one side of an RFQ.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Commercial information is also needed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Include:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Quantity: [required quantity]<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">and, where relevant:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Required delivery date: [target date]<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">or:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Project schedule: [required schedule]<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">If the project will be purchased in several batches, mention that as well.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This helps separate:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>prototype requirement<\/li>\n\n\n<li>pilot order<\/li>\n\n\n<li>production order<\/li>\n\n\n<li>recurring demand<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">without requiring the supplier to guess the commercial scale.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"oem-requirements\">13. Packaging, Labeling and OEM Requirements<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Buyers may also have project-specific commercial requirements such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>packaging format<\/li>\n\n\n<li>carton labeling<\/li>\n\n\n<li>product identification<\/li>\n\n\n<li>documentation format<\/li>\n\n\n<li>OEM branding or private labeling<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These are reasonable items to include in an RFQ when they matter.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, availability should be confirmed for the exact product, quantity and project.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The RFQ should therefore use wording such as:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Packaging \/ labeling requirement: [requirement]<\/p>\n<\/blockquote>\n\n\n\n<blockquote class=\"wp-block-quote

Template<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The following template is intentionally non-engineering-specific.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Replace the placeholders with

class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Other project requirements: [additional information]<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">This template helps communicate existing requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It should not be used to invent electrical parameters that the project has not yet determined.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"unknown-parameters\">What If Some Parameters Are Not Yet Known?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">It is acceptable for an RFQ to contain unknown items.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Trip curve: To be confirmed by project engineer<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">is better than guessing a curve simply to fill the field.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Likewise:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Breaking capacity: Project requirement pending<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">is clearer than assuming 6kA or 10kA from the building type.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The supplier can identify which information is missing for product matching, while the project team remains responsible for requirements that belong to electrical design.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"common-mistakes\">Common AC MCB RFQ Mistakes<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Sending Only the Current Rating<\/h3>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">\u201c32A MCB\u201d leaves major questions unanswered.<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">Voltage, poles, trip curve and breaking capacity may still be needed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Leaving Out Pole Configuration<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A 32A 1P+N breaker and a 32A 2P breaker are not the same configuration.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Asking for \u201cStandard Curve\u201d<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">There may be several curve options.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Specify the required curve if the project has already defined it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Saying \u201c6kA or 10kA \u2014 Whichever Is Better\u201d<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Breaking capacity is not a quality ranking.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Provide the required short-circuit rating from the project specification.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Asking for \u201cIEC Certified\u201d Without Naming the Requirement<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A standard reference, test report and market approval are not necessarily the same thing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Specify the actual documentation needed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Forgetting Variant-Dependent Data<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Some values may vary by exact model or option.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, RTS-ACM60 currently describes 6kA as typical and subject to variant confirmation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Assuming a Configuration Label Defines Neutral Behavior<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If neutral switching or protection is important, request that information explicitly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Assuming OEM Branding Is Automatically Available<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Include the requirement in the RFQ and ask for confirmation for the exact product and quantity.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"rfq-workflow\">A Practical RFQ Workflow<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A simple
