Further Abb circuit breaker combinations:

The residual current circuit breakeris located next to the circuit breaker and integrates a magnetic protection to a thermal one, and in case of need it interrupts the electric current.

 

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

 

The residual current circuit breakerin 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 power supply (e.g., more than one appliance in operation);
  • the differential one proper to the circuit breaker, which protects the subject from a current leakage

     

Curve C, trip threshold of 5 to 10 times In, for application of ohmic-inductive circuits with medium inrush currents. And widely used in domestic systems.


 

The AC-type differential circuit breaker the tripping is assured for suddenly or slowly increasing applied sine-sine differential alternating currents (IEC EN 61008-1).

 

The DS203C differential circuit breaker is a 3P+N device in 4 modules for protection of circuits against overload and short circuit; available with trip curves B and C and rated currents up to 32A it allows protection against the effects of alternating sine wave currents (type AC) sine wave and continuous currents with pulsating components (Type A) also in a version resistant to untimely trips (APR).
