An MPCB’s adjustable motor-current range does not tell you whether it can interrupt the short circuit available at the panel. Breaking capacity is a separate rating tied to the device, system voltage and applicable test conditions. Buyers need the prospective fault current at the MPCB location and exact-model interruption evidence before approving a motor-control bill of materials.<\/p>\n

Bir motor dal\u0131ndaki beklenen ak\u0131m, transformat\u00f6r ve kaynak empedans\u0131na, kablolara, yukar\u0131 ak\u0131\u015ftaki ekipmana ve tam kurulum noktas\u0131na ba\u011fl\u0131d\u0131r.

Record the study’s assumptions and the operating configurations it covers. Alternate supplies, generator operation or future transformer changes can alter fault duty. If the study is incomplete, identify the breaker selection as provisional. A supplier may suggest candidates but cannot validate the installation from motor power alone.<\/p>\n

Keep the fault level separate from the motor’s normal and starting current. The MPCB has to carry and protect the motor under ordinary duty and also interrupt or participate in clearing a much higher fault. One ampere label cannot stand for both jobs.<\/p>\n

Gerilimi kesinti tablosundaki de\u011ferle tam olarak e\u015fle\u015ftirin<\/h2>\n

Breaking capacity may vary substantially across voltage values for one model. Schneider Electric’s published motor-circuit-breaker datasheets show different Icu and Ics entries at different AC voltages. The numbers are Schneider product values, not a RITOKS specification; they demonstrate why the exact system voltage belongs beside the rating.<\/p>\n

Ask for the exact device order code, pole configuration, rated operational voltage and short-circuit table. Do not compare a candidate’s best-looking rating at a lower voltage with the project’s higher-voltage duty. Note frequency and any conditional or upstream-protection requirement in the data.<\/p>\n

ICU ve ICS\u2019yi birbiriyle birle\u015ftirmeden anlamak<\/h2>\n

IEC-style product data may distinguish ultimate short-circuit breaking capacity, Icu, from service short-circuit breaking capacity, Ics. The two refer to different test and post-fault performance criteria. Schneider Electric’s user guide describes Ics as a service rating expressed relative to Icu for its devices. Do not treat the values as synonyms or assume their relationship is the same for every model.<\/p>\n

Proje \u015fartnamesinde, ge\u00e7erli standart ve yerel gereklilikler kapsam\u0131nda hangi de\u011ferlerin kontrol edilmesi gerekti\u011fi belirtilmelidir. Bir ar\u0131za sonras\u0131nda kesiciden ne beklenebilece\u011fini ve \u015fantiyede hangi inceleme veya de\u011fi\u015ftirme prosed\u00fcr\u00fcn\u00fcn izlenece\u011fini sorun. Ar\u0131za giderme i\u015flemi, cihaz\u0131n hizmet kesme kapasitesi de\u011ferine sahip olsa bile rutin bir anahtarlama i\u015flemi de\u011fildir.<\/p>\n

Do not infer the exact device’s Ics from a family brochure or a competitor product. Obtain the model-specific table at the project voltage and record it with the design. If the supplier gives Ics as a percentage of Icu, calculate or quote the corresponding value using that model’s data, not a generic rule.<\/p>\n

Ba\u015flang\u0131\u00e7 kombinasyonlar\u0131n\u0131 ve koordinasyonu g\u00f6zden ge\u00e7irin<\/h2>\n

Bir MPCB genellikle bir kontakt\u00f6r ve di\u011fer devre ba\u015flatma bile\u015fenleriyle birlikte kullan\u0131l\u0131r. Bu kombinasyonun k\u0131sa devre durumunda g\u00f6sterdi\u011fi performans, kendine \u00f6zg\u00fc bir test edilmi\u015f koordinasyon esas\u0131na dayanabilir. \u00dcreticinin koordinasyon tablolar\u0131, ilgili cihazlar\u0131 ve ko\u015fullar\u0131 kesin olarak belirtmelidir. Benzer boyutlarda bir kontakt\u00f6r veya de\u011fi\u015ftirilmi\u015f bir a\u015f\u0131r\u0131 y\u00fck bile\u015feni, \u00f6nceki sonucu garanti edemeyebilir.<\/p>\n

Ask whether the cited fault rating is for the MPCB alone or conditional on a specified upstream device or combination. Record any required fuse, contactor, busbar or terminal accessory. The result should be checked against the panel’s prospective fault current and applicable assembly design requirements.<\/p>\n

Schneider Electric’s motor-starter catalogue provides examples of coordinated combinations, but those tables are not transferable to unrelated RITOKS devices. Request RITOKS-specific evidence where a combination claim is necessary. Without it, keep the assembly rating question unresolved.<\/p>\n
