2 Electrical Appliance and Material Safety Law of Japan

Motor protection breakers

Motors are nor mally controlled by

MCCBs and magnetic starters. In this

case the MCCB carries out overcurrent

or short-circuit current protection while

the starter deals with ON-OFF switching

of the motor and offers protection against

sustained overload currents. These are

the motor breakers which combine the

two functions.

FUJI motor breakers are designed to

eliminate erroneous operations due to

the rush current produced at the time of

starting the motor. They will trip in the

face of sustained overcurrent when the

integrated bimetal relay has operated.
