Further Chint RCBO combinations:

The Residual Current Operated 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 Residual Current Operated Circuit Breaker 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 earth leakage circuit breaker, which protects the subject from a current leakage

     

The Residual Current Operated Circuit Breaker type A tripping is ensured for alternating sine differential currents and unidirectional pulsating differential currents applied suddenly or slowly increasing (IEC 61008-1).

 

NB1L1 series 4.5 kA magnetothermal/differential circuit breakers. Particularly suitable for line protection against overloads and short circuits, as well as against direct contacts. Intended for civil, tertiary and industrial applications.
