Optional Parts and Accessories

Optional Parts and Accessories

There are many optional units for motor protection relays.

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

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.
