Description

The AC Residual Current Circuit breaker is a safety appliance that protects personal safety and prevents electrical fires, can prevent electrical equipment from being damaged. It can be widely used in power distribution systems.

 

Product Benefits :

  • Air circulation
    When two poles are placed adjacent to each other, these channels form a tunnel resulting in effective air circulation around individual poles
  • Bi-connect Termination Possible
    Choice to use Busbar and/or cable in the same terminal,provides reliable termination
  • Din Rail Mounting
    Two step snapping mechanism for easy & efficient mountion in 35mm DIN Rail steadily
