Outline installation dimensions and circuit schematic diagram
1. The length of main circuit connecting bolt of conventional products is M8*20.8mm（See the attached figure）；
If you have special needs, you can customize the lengthened bolt model, and added（.L）, as WSW80/48.L；
2. The model of additional products in brackets is not shown on the nameplate.
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.
