The thermal-magnetic circuit breaker is located next to the circuit breaker and combines magnetic and thermal protection and, if necessary, interrupts the electrical current.

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

The thermal-magnetic differential switch in the electrical system integrates three different protections:

• the magnetic one for short circuits that can put an entire building at risk of fire;
• the thermal one for overloads in the supply of electrical energy (e.g. more than one household appliance in operation);
• the differential which protects the subject from a current leakage.
  
  

The C curve, trip threshold from 5 to 10 times In, for application of ohmic-inductive circuits with medium inrush currents. It is widely used in domestic installations.

The AC residual current circuit breaker type the tripping is ensured for suddenly or slowly increasing applied sinusoidal alternating currents (CEI EN 61008-1).
