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 type A residual current circuit breaker tripping is ensured for alternating sinusoidal differential currents and unidirectional pulsating differential currents applied suddenly or slowly increasing (CEI EN 61008-1).
