Phase Failure Protection Relay/ Protective Relay/Motor Protector/Protection/Under Voltage Protection Relay
Phase Failure Protection Relay / Protective Relay /Motor Protector/ Protection/Controller (HHD10-D)

HHD Series motor protector /Phase Failure Protection Relay can be used in the circuit of alternating current 50Hz, rated working current 380V.
Motor control circuit can be formed by combining motor protectors with switching apparatus like AC contactors. When the abnormal working states(such as phase failure, overloading, three-phase unbalance, overvoltage, undervoltage, short circuit etc. ) emerge in the main circuit of motors, motors can be protected quickly and reliably by breaking switch and disconnecting three-phase power.
