Motor Protector

It constitutes controlling circuit of electrical motor with AC contactor and other switching apparatus. When abnormal working condition occurred in the main circuit of electrical motor, such as phase failure, overload, block, 3-phase imbalance, leakage and so on, the motor protector will make contacts of switching apparatus switched off immediately, disconnect 3-phase power of electrical motor to achieve result of motor protection quickly and safely.
