  • Product Detail

This circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body, which can be used as a fixed installation unit or equipped with a special propulsion mechanism to form a handcart unit.


①  The pole body of the circuit breaker adopts A-pole compound rubber, which can play a very good anti-fouling and sealing effect, and its wear resistance is stronger than ordinary materials.

② Plum-style copper contacts are less prone to rust and damage, and have a long service life.

③ Install metal wheels for easy movement and better installation efficiency.

④ Vacuum arc extinguishing chamber, with strong arc extinguishing insulation, long life, small size and stable safety performance.
