Chint Circuit Breaker NBH8-40 1P+N 32A 4.5kA C 1 Module 190239

Compact circuit breakers NBH8-40 series designed to occupy the space of a single DIN module. Suitable for overcurrent circuit protection and particularly suitable for overload and short-circuit protection in terminal distribution. Can be accessorized with auxiliary contacts, alarm contacts, trip coil and minimum voltage coil.

 

A circuit breaker is a safety device that can automatically (i.e., without external intervention) interrupt 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 systems.
