Motor Circuit Breakers

Integration of Low Voltage Circuit Breakers and Thermal Overload Relay functions.

This device is capable of protecting motor branch circuits from overload, phase-loss, and short-circuit.
It offers even more secure wiring and motor protection.

Motor Circuit Breakers

Space-saving design has lead to down-sizing of the control panel.
The rated short-circuit breaking capacity satisfies 10KA at a voltage of 200-240VAC.
