HHD7-F/M Intelligent type corotation/inversion controller

HHD Series motor protector 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.
HHD Series motor protectors conform to GB14048.4 standard and got CCC approval.
