Give the supply voltage and frequency at the breaker, the earthing system where relevant and the prospective short-circuit current at the installation point. Ask for the exact MPCB’s breaking-capacity evidence at the applicable voltage. A motor-current match is not enough if the available fault level exceeds the documented device capability.<\/p>\n

Identify upstream fuses or breakers and any downstream contactor or overload device. The panel designer should determine whether coordination or selectivity requirements apply and obtain tested combinations where needed. Schneider Electric’s motor-starter coordination tables show that protection and control devices are reviewed as combinations; a similar-looking part is not automatically part of the tested arrangement.<\/p>\n
