The Residual Current Operated Circuit Breaker is, therefore, a system that combines the functions of the circuit breaker with magnetic and thermal characteristics.
The Residual Current Operated 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);
- that differential proper of the circuit breaker that protects the subject from a power leakage.
AC type Residual Current Operated Circuit Breaker, the tripping is ensured for suddenly or slowly increasing applied sinusoidal alternating differential currents (IEC EN 61008-1).
