Motor protection circuit-breaker EC000074

Motor-protective circuit-breakers are circuit-breakers used for the switching, protection and isolation of circuits primarily associated with motor loads. At the same time, they protect these motors against destruction from locked-motor starting, overload, short-circuit and phase-failure in three-phase power supplies. They have a thermal trip block or an electronic release for protecting of the motor winding (overload protection) and an electromagnetic release (short-circuit protective device).
