The thermomagnetic circuit breaker is located next to the circuit breaker and integrates a magnetic protection with a thermal one and interrupts the electric current in case of need.

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 present 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 (for example, more than one household appliance in operation);
• the differential one, typical of the lifesaver, which protects the subject from a current leakage.
  
  

The AC type differential switch intervention is ensured for sinusoidal alternating currents applied suddenly or slowly increasing (CEI EN 61008-1).
