Chint Circuit Breaker NB1-63 3P 50A 6kA C 3 Modules 180382

Circuit breakers NB1-63 series for overcurrent protection. They provide adequate protection against overloads and short circuits and are particularly suitable for use in civil, tertiary and industrial applications. They can be accessorized with auxiliary contacts, alarm contacts, trip coil, minimum voltage coil, differential modules (except single-pole).

 

A circuit breaker is a safety device capable of automatically (i.e., without external intervention) interrupting the flow of electric current in an electrical circuit in the event of an overcurrent.

 

The C-curve can tolerate short-term overcurrents of up to five to ten times the rated current and is widely used in domestic installations.
