The residual current circuit breaker is 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 breaker is, therefore, a system that combines the functions of the circuit breaker with magnetic and thermal features.
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 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 ensured for suddenly or slowly increasing applied sine differential alternating currents (IEC EN 61008-1).
The RCBO DS202CR series is a 2P device in two modules for protection of single-phase end-user circuits against overload and short-circuit currents. Protection against the effects of alternating and direct pulsating sinusoidal earth fault currents. Protection against indirect and additional contacts. Final protection against direct contacts.
