Moulded Case Circuit Breaker

The EXM3 moulded case circuit breakers (hereafter as the MCCBs) are suitable for use in electric systems of AC 50Hz/60Hz, with the rated insulation voltage of up to 1000V (800V for 125A and below frames) and rated current up to 630A, to distribute electrical energy, protect circuits and power equipment from hazards due to overload, shortcircuit, under-voltage, and other faults, and control infrequent motor operations. The EXM3 MCCBs offer Type C (basic), Type S (standard), and Type H (high breaking) based on its rated ultimate short-circuit breaking capacity, and feature small size, high breaking capacity, and short arcing distance.
