Product Description

Products Description

 

 

 

 

 

 

working principle:


     When an overloaded circuit or short-circuit current occurs, the current sensor transmits the collected current signals to the intelligent controller.

      The intelligent controller then issues a trip command to energize the tripping coil, which releases the energy-stored spring in the operating mechanism.

     This causes the contacts to rapidly separate,Create a vacuum environment within the vacuum tube. extinguishing the arc.
 

 

 

The difference between handcart type and fixed type

      Handcart-type vacuum circuit breaker: Installed on the handcart cabinet, it has a chassis cart and contact arm, allowing for convenient movement and extraction. This design makes the handcart-type circuit breaker more flexible during maintenance and inspection.
      Fixed-type vacuum circuit breaker: Installed directly in the fixed cabinet, without a chassis cart and contact arm, thus unable to move.
