ABB residual current circuit breaker 1P+N 20A 30mA 6KA AC Type 2 Modules DS201C20AC30

The residual current circuit breaker is, therefore, a system that combines the functions of the circuit breaker with magnetic and thermal characteristics.


 

The residual current circuit breaker in the electrical system integrates three different protections:

• the magnetic one for short circuits that can endanger an entire building with the danger of fire
• the thermal one for overloads in the supply of electricity (for example, more than one appliance in operation)
• the differential one proper to the earth leakage circuit breaker, which protects the subject from a current leakage
  
  
   

The AC type residual current circuit breaker the tripping is ensured for suddenly or slowly increasing applied sine differential alternating currents.
