Motor circuit breaker features

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.
A motor circuit consisting of a Low voltage circuit breakers, 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 an Contactor, only motor control is provided by the Contactor ond other functions are provided by the Motor circuit breaker.

What is a Motor circuit breaker?

A Motor circuit breaker is a device integrating Low voltage circuit breakers and Thermal Overload Relays functions.
This device is capable of protecting the motor branch circuits from overload, phase-loss, and short-circuit alone.
It enable even more secure wiring and motor protection.

What is the role of a Motor circuit breaker in a motor circuit?

The motor circuit requires various roles, including disconnection, circuit on/off switching, short-circuit protection, device protection, motor control, and overload protection. A motor circuit consisting of a Low voltage circuit breakers, Magnetic 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 an Magnetic Contactor, only motor control is provided by the Magnetic Contactor and other functions are provided by the Motor circuit breaker.
