Overcurrent circuit breaker, 6kA series BKN 1P 63A B characteristic BKN 1P B63A

Safety and reliability in your installation

This single-pole circuit breaker from the BKN series, with a rated current of 63A and B characteristic, is a key element in protecting the electrical installation. It provides effective protection against overload and short circuit, protecting both devices and the electrical installation. The B characteristic means that the breaker reacts quickly to current increase, but allows for short-term peak loads – which is particularly important when connecting devices with motors or other loads with high inrush current.

Design and installation

The BKN 1P B63A circuit breaker is designed for mounting on a DIN rail, which simplifies and speeds up its installation in the distribution board. Its compact size – occupying only one module – allows for optimal use of space in the switchgear cabinet. The IP20 degree of protection provides basic protection against contact and ingress of solid objects.

Operating parameters and application

The circuit breaker is adapted to work in networks with a rated voltage of 230/400V AC. Its short-circuit strength is 6kA, which guarantees its proper operation even in the event of a failure. This makes it suitable for protecting lighting circuits, socket circuits and other electrical devices with moderate power consumption. The choice of B characteristic makes it a good choice for protecting circuits with inductive loads.
