Hager 4P 40A 300MA B Magnetothermal Residual Current Circuit Breaker 4 Modules CFB640E

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

The magneto-thermal differential switch 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 supply of electricity (for example, more than one appliance in operation
• the differential one proper to the earth leakage circuit breaker, which protects the subject from a power leakage
  
  

The AC type differential circuit breaker the tripping is ensured for suddenly or slowly increasing applied sine differential alternating currents (IEC EN 61008-1).
