Overcurrent circuit breaker, 6kA BKN series 1P 1A B characteristic BKN 1P B1A

Overcurrent circuit breaker BKN series – reliable installation protection

The BKN series installation circuit breaker is a compact device designed to protect electrical circuits against overload and short circuit. Model BKN 1P B1A, with a rated current of 1A and B characteristic, provides effective protection in installations with a voltage of 230/400V AC. Its versatility makes it suitable for use in both domestic and commercial installations.

Construction and mounting

The BKN 1P B1A circuit breaker is designed for mounting on a standard 35mm DIN rail. Its modular construction (1 module wide) allows for optimal use of space in the distribution board. Solid construction guarantees durability and reliable operation for a long time. The device is adapted to cooperate with wires with a cross-section of up to 2.5mm², which facilitates its integration with the existing electrical infrastructure.

Characteristics and application

The B characteristic of the circuit breaker means that its operating time is adapted to loads with short-term current surges, such as motors or transformers. This ensures that the device does not switch off unnecessarily when starting these devices, while effectively reacting to overloads and short circuits, protecting the installation from damage. This circuit breaker is ideal for lighting circuits, socket circuits and for protecting electrical devices with low power consumption. It provides protection against the effects of overloads and short circuits – like any circuit breaker of this type – but its characteristic makes it particularly well suited to the specifics of certain loads.

Operating parameters and safety

The BKN 1P B1A circuit breaker has a short-circuit breaking capacity of 6kA at a voltage of 230/400V AC, which guarantees safe disconnection of the circuit in the event of a serious failure. The IP20 degree of protection provides protection against accidental contact and against the ingress of solid objects larger than 12.5 mm. The device meets the requirements of IEC standards, which confirms its compliance with applicable safety standards.
