Overcurrent circuit breaker, 6kA BKN series 4P 4A B characteristic BKN 4P B4A

Safety and reliability in your electrical installation

This four-pole miniature circuit breaker of the BKN series, with a rated current of 4A and B characteristic, is a key element ensuring protection in electrical circuits. Designed for DIN rail mounting, it provides reliable protection against overloads and short circuits. Its compact dimensions and high efficiency make it ideal for both new installations and modernization of existing ones.

Protection tailored to your needs

The BKN 4P B4A circuit breaker is characterized by a B characteristic, which means it is particularly well suited for protecting circuits with receivers with moderate inrush current. This makes it perfect for installations powering lighting, sockets, and household appliances. It provides a quick response in the event of a dangerous current increase, minimizing the risk of equipment damage and fire. Its short-circuit breaking capacity is 6kA – a parameter guaranteeing effective disconnection of the circuit in the event of a failure.
