Overcurrent circuit breaker, 6kA BKN series 1P 25A characteristic C BKN 1P C25A

Overcurrent circuit breaker – reliable protection for your installation

This single-pole circuit breaker from the BKN series, with a rated current of 25A and C characteristic, is a key element ensuring safety in every electrical installation. Designed to protect against the effects of overloads and short circuits, it performs well in both domestic and industrial applications. Its compact size (1 module width) makes it easy to install in electrical distribution boards.

Construction and application

The BKN 1P C25A circuit breaker is designed to protect circuits with a rated voltage of 230/400V AC. The C characteristic means that the circuit breaker reacts with a delay to short-term current surges, which is particularly important when connecting devices with motors or other loads generating high inrush currents. This minimizes the risk of unnecessary tripping of the circuit during normal operation of devices. The short-circuit breaking capacity of 6kA guarantees effective protection in the event of serious failures.

• Versatile application: ideal for protecting lighting, sockets, household appliances and other electrical circuits.
• DIN rail mounting: quick and easy mounting on a standard TH35 rail allows for seamless integration with an existing distribution board.
• Compact size: occupies only 1 module width, saving space in the distribution board.
• Reusable: after tripping, it can be re-engaged, eliminating the need for frequent replacement as with traditional fuses.
• Complies with standards: meets the requirements of EN 60898 standard, ensuring a high level of safety and reliability.

Parameters and design features

The BKN 1P C25A circuit breaker is made of high-quality materials, guaranteeing its durability and reliable operation for a long time. It has a protection class of IP20, which provides protection against accidental contact. Thanks to the precise C tripping characteristic, it ensures optimal selectivity of operation and minimizes the risk of false alarms. Designed to operate in ambient temperatures from -5°C to 40°C. The rated short-circuit breaking capacity Icn is 6kA at 400V – a key parameter for ensuring effective protection of the installation against the effects of short circuits.
