Application

Matters needing attention

1.When installing the contactor, the tightening torque of the main circuit wiring screw nut is 8～10N.m;

Control circuit wiring screw nut tightening torque 1～1.5N.m.

2.The driving circuit power of the product coil must be greater than or equal to the product coil power,

Otherwise the cutting capacity of the product will be reduced.

3.The voltage continuously applied to the coil shall not exceed the maximum allowable voltage.

Otherwise, the abnormal heating of the coil will shorten the life of the insulation layer.

Example：WZLJ-200D/48；Indicates: the main contact is normall open,the rated voltage is not greater than DC48V,the current is 200A,and the coil voltage is DC48V DC contactor.
