Overcurrent circuit breaker, 6kA series BKN 3P 63A B characteristic BKN 3P B63A

Electrical installation protection with BKN 3P B63A circuit breaker

The BKN 3P B63A overcurrent circuit breaker is a reliable protection for your electrical installation. Designed to protect circuits against overloads and short circuits, it ensures safe and stable operation of devices. Thanks to its B characteristic, this circuit breaker is perfect for applications where short-term current surges occur, such as starting electric motors or devices with heating elements. The rated short-circuit breaking capacity of 6kA guarantees effective intervention in the event of a failure, minimizing the risk of damage and fires.

### Construction and application

The three-pole BKN 3P B63A circuit breaker is mounted on a DIN rail, which facilitates its installation and integration with the existing electrical system. The device's width of 3 modules allows for efficient use of space in the distribution box. The IP20 degree of protection provides protection against accidental contact and the ingress of solid objects larger than 12.5 mm. This circuit breaker is used in building installations – both residential and commercial – as well as in industrial facilities. It is ideal for protecting lighting circuits, socket outlets and electrical devices with a power of up to 63A.

### Key features and benefits

* **B characteristic:** provides a quick response to overloads and short circuits, while allowing short-term exceedances of the rated current without unnecessary tripping. This is particularly important when handling devices with induction motors or other loads with high starting current. * **Short-circuit breaking capacity 6kA:** guarantees effective disconnection of the circuit in the event of a short circuit, protecting devices and the installation from serious damage. * **DIN rail mounting:** facilitates and speeds up installation and replacement of the circuit breaker. * **Three-pole design:** provides comprehensive protection for the entire circuit. * **Width 3 modules:** allows for optimal use of space in the distribution box. * **Rated voltage 400V AC:** enables use in standard power networks. * **Degree of protection IP20:** increases safety by protecting against accidental contact and the ingress of solid objects.

The BKN 3P B63A circuit breaker is a solid and reliable solution for anyone who cares about the safety of their electrical installation. Its versatility makes it ideal for both professional installers and end users looking for effective protection for their devices and home.
