Interrupting direct current is different from interrupting AC because the current does not naturally cross zero every cycle. Some MCCB designs use more than one pole in series along a current path to achieve a documented voltage capability. Schneider Electric’s DC MCCB documentation shows examples of series and parallel pole connections; those are product-specific schemes, not general permission to rewire another breaker.<\/p>\n

Ask which rating table applies to the proposed wiring, including rated operational voltage, breaking capacity and continuous current.

Series-pole connection and parallel-pole connection address different design questions. Series arrangements can be used in specific products to support a higher DC voltage. Parallel arrangements may be offered in specific designs for current capability. Neither is a general field modification.

DC kesme verilerini ayn\u0131 esaslara g\u00f6re do\u011frulay\u0131n<\/h2>\n

A DC MCCB’s continuous-current rating does not tell you its interrupting duty. Compare the location-specific prospective fault current with the manufacturer’s DC breaking-capacity data at the actual operating voltage and pole connection. Ask whether the rating is ultimate, service or another defined measure under the applicable standard and what post-fault service assumptions are made.<\/p>\n
