Explosion proof magnetic starter for crane operationProduct Features

The shell is made of aluminum alloy die-casting, 304 stainless steel (or Q235 steel plate) welding, etc. The aluminum alloy and Q235 steel plate shell are subjected to high-voltage electrostatic spraying, and the welded shell surface is treated with wire drawing;

This product has a composite structure, with the main chamber adopting explosion-proof form and the wiring chamber adopting increased safety form;

3. Adopting modular design, each circuit can be freely combined;

4. Equipped with high breaking miniature circuit breakers, molded case circuit breakers, AC contactors, transfer switches, thermal relays, etc., the opening and closing can be achieved by operating the handle on the shell cover, which is equipped with a connection indicator light;

5. It has overload and short circuit protection functions, and can produce products with leakage protection function according to user requirements;

6 can be used for distribution or switching of lighting circuits or power circuits, as well as for magnetic starting, power maintenance, or mixed use of switching;

7 can be customized according to user requirements;

8 steel pipes or cable wiring.
