Earth leakage circuit breaker Hager 1P+N 300MA 20A AFA820H
Tax included
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 differential switch type A tripping is assured for differential sinusoidal alternating currents and for pulsating differential unidirectional currents applied suddenly or slowly increasing (CEI EN 61008-1).
