Direct-on-line starting, heavy-load startup, and frequent starts may affect the practical selection, especially if the breaker is set too close to the operating current.<\/p>\n\n\n\n<p>Then confirm the system voltage, short-circuit level, and installation environment.

selecting the breaker only by motor kilowatt value without checking the actual rated current on the motor nameplate.<\/p>\n\n\n\n<p>Another mistake is ignoring startup behavior. If the setting is too low, nuisance tripping may occur during motor startup. If the setting is too high, the motor may not be adequately protected under overload conditions.<\/p>\n\n\n\n<p>Buyers should also confirm coordination with contactors, overload relays, and the rest of the motor starter design instead of selecting the MPCB as a standalone component.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\"
