Overcurrent circuit breaker, 6kA series BKN 4P 40A B characteristic BKN 4P B40A

Protection of installations and devices – 4-pole overcurrent circuit breaker

This four-pole overcurrent circuit breaker from the BKN series, with a rated current of 40A, is a reliable protection for your electrical installation. Designed to protect circuits against overload and short circuit, it ensures safe use and minimizes the risk of failure. Its compact size makes it easy to install in distribution boards, and its high quality of workmanship guarantees long-lasting and trouble-free operation.

Characteristics and application

A circuit breaker with characteristic B is particularly recommended for protecting lighting circuits and sockets in residential and commercial buildings. Characteristic B means that the circuit breaker reacts quickly to an increase in short-circuit current, but is less sensitive to short-term current surges that may occur during the starting of motors or other devices with high power consumption. This reduces the risk of unnecessary tripping of the circuit. The rated breaking capacity of 6kA at 400V AC provides effective protection in the event of serious disturbances in the network.

Installation and reliability

The circuit breaker is designed for mounting on TH35 rail (standard rail). The solid construction and precise workmanship guarantee stable operation for a long time. By choosing this circuit breaker, you are investing in safety and peace of mind – both you and your customers can be sure of reliable protection of the electrical installation.
