ABB Thermal-magnetic circuit breaker 4P 16A 30mA 6KA AC Type 4 Modules DS3NC16AC30

Thermal-magnetic circuit breaker ential is, therefore, a system that combines the functions of the circuit breaker with magnetic and thermal characteristics.


 

The magnetothermal 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 current leakage
  
  
   

The AC-type differential circuit breaker the tripping is ensured for suddenly or slowly increasing applied sine-sine differential alternating currents.
