Overcurrent circuit breaker, 10kA BKH series 4P 125A characteristic C BKH 4P C125A

Overcurrent circuit breakers of the BKH series – reliable protection of installations

The BKH series overcurrent circuit breaker is a protection element for electrical installations, designed to protect against the effects of overloads and short circuits. The 4P model with a rated current of 125A and a breaking capacity of 10kA provides effective protection in demanding applications. It is characterized by high reliability and durability, making it an ideal solution for both home and industrial installations. The design based on four poles (4P) allows you to disconnect all phase conductors simultaneously, increasing safety.

Construction and application

The BKH 4P C125A circuit breaker is designed for mounting on a 35mm DIN rail, which facilitates its installation and replacement. Its compact dimensions allow for efficient use of space in electrical switchboards. Characteristic C provides a delayed response to short-term current increases, which is particularly important when connecting devices with motors or other inductive loads. This prevents the circuit breaker from tripping unnecessarily when starting such devices, while effectively reacting to overloads and short circuits. It finds application in electrical power distribution networks, providing protection against damage and fires caused by failures in the installation.
