Abb 40A 30mA 1P+N 1P+N Type A 6KA Differential Circuit Breaker 2 Modules DS201C40A30

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 power supply (e.g., more than one appliance in operation);
• the differential one proper to the circuit breaker, which protects the subject from a power leakage.
  
  

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

Type A differential circuit breaker, tripping is assured for alternating sine differential currents and unidirectional pulsating differential currents applied suddenly or slowly increasing (IEC EN 61008-1).
