Motor Circuit Breakers

A Motor circuit breaker is a device integrating Low voltage circuit breakers and Thermal overload relays functions.
The motor circuit requires various roles, including disconnection, circuit on/off switching, short-circuit protection, device protection, motor control, and overload protection.

Space-saving design has realized down-sizing of the control panel
Basic Type: MMP-T32
Rated current(A):0.6 to 32
Dimension mm(W x H x D):45 x 96 x 76

A motor circuit consisting of a Low voltage circuit breaker, Contactor, and Thermal Overload Relays is typically adopted and each of the devices has its own independent role. On the other hand, in a motor circuit consisting of a Motor circuit breaker and a Contactor, only motor control is provided by the Contactor and other functions are provided by the Motor circuit breaker.
