Overcurrent circuit breaker, 6kA series BKN 3P 50A characteristic D BKN 3P D50A

Electrical installation protection with BKN 3P D50A circuit breaker

This three-pole circuit breaker from the BKN series, with a rated current of 50A and D characteristic, is a reliable protection for your installation. Designed to protect against overload and short circuit, it performs well in circuits exposed to high inrush currents – for example, when connecting devices with electric motors. Its construction and parameters ensure effective protection, and its compact dimensions facilitate mounting in distribution boards.

Characteristics and application

The BKN 3P D50A circuit breaker is characterized by a high short-circuit breaking capacity – as much as 6kA. This means that it is able to safely interrupt the circuit in the event of a serious failure, minimizing the risk of damage and fire. The D characteristic provides a delayed tripping time for short-term overloads, which is particularly important for devices generating high starting currents. This will avoid unnecessary tripping of the circuit during normal operation.

• Rated current: 50A – ideal for protecting circuits with higher power demand.
• Characteristic D: provides resistance to short-term overloads, typical for devices with motors.
• Short-circuit breaking capacity: 6kA – a high value guarantees effective protection in the event of a failure.
• Number of poles: 3P – designed to protect three-phase electrical circuits.

BKN series BKN circuit breakers are widely used in installations:

• Home and residential
• Commercial (offices, shops)
• Industrial (workshops, production halls)
• When powering electric motors and other devices generating high inrush currents.

The installation and operation of this circuit breaker is intuitive for both experienced installers and end users. The solid construction guarantees long-lasting and trouble-free operation.
