Overcurrent circuit breaker, 6kA series BKN 3P 1A B characteristic BKN 3P B1A

Electrical installation protection with BKN 3P B1A circuit breaker

This three-pole circuit breaker from the BKN series, with a rated current of 1A and B characteristic, is a reliable element for protecting electrical installations. Designed by LS Electric, it provides effective protection against overloads and short circuits, minimizing the risk of damage and fires. Its design and parameters make it suitable for both domestic and professional applications.

Characteristics and application

The BKN 3P B1A circuit breaker is characterized by a B tripping curve, which means it is particularly well suited for protecting circuits with receivers with high inrush current – such as electric motors or transformers. The B curve allows for short-term exceeding of the rated current without unnecessary tripping, which is crucial for the correct operation of these devices. The short-circuit current of the circuit breaker is 6kA at 400V, which guarantees a quick and effective response in the event of a failure.

Construction and installation

The BKN 3P B1A circuit breaker has been designed with easy mounting on a TH35 rail in mind. The three-pole design provides comprehensive protection for the entire circuit. Compact dimensions allow for installation in switchboards with limited space. Solid construction guarantees long-lasting and trouble-free operation. Installation should be carried out by a qualified electrician in accordance with applicable standards and regulations.

Key product features:

• Rated current: 1A – ideal for protecting circuits with low power consumption.
• B characteristic: provides protection against overloads and short circuits, and also allows for starting devices with high inrush current.
• Three-pole design (3P): comprehensive protection of the entire circuit.
• Short-circuit current: 6kA/400V – quick response in the event of a failure.
• Mounting on TH35 rail: easy and quick mounting in the switchboard.
• Compliance with standards: ensures safety and reliable operation (detailed standards should be checked in the technical documentation).
• Compact dimensions: facilitate installation in tight spaces.

Thanks to these features, the BKN 3P B1A circuit breaker is an optimal solution for a wide range of applications in residential, commercial and industrial construction.
