■ Product Model
Example: BZJ-800A/48; said: Normally closed DC Contactor, 800A for DC-1 load rated current, coil voltage 48V DC.
■ Shape installation and circuit diagram
■ Remarks
1. While assemble contactor, tighten torque of nut of terminal screw in main circuit is 14~17.5N.m; tighten torque of nut of terminal screw in control circuit is 1~1.5N.m.
2. Driving circuit power for coil must be no less than coil power; otherwise, it will reduce cutting capacity of product.
3. Continuous applied voltage should not exceed the maximum permission voltage. Otherwise, abnormal
heating of coil will shorten the life of insulating coating.
4. This contactor is non-waterproof, please don’t use in water, solvent, oil and other environment that may contact with the shell or terminal. Otherwise, it may cause abnormal heating due to the burn-in of shell or corrosion, dirty of terminal.
