Circuit breaker HMMS
Hyundai Motor Circuit Breakers (HMMS series), combines role of circuit breakers and bimetal-thermal relays. These breakers protect 3-phase motors
against overload, phase failure, short circuit and too frequent activations.
They have thermal releases for protection motor winding (overload protection) and an electromagnetic releases (short circuit protection). Their high breaking capacity permits exclusion of fuses in most of installations. HMMS series can be use also to protect low-voltage distribution lines, because it meets the requirements of the IEC 60947 and IEC60947-4-1 standards..
