Overcurrent circuit breaker, 6kA BKN series 1P 40A D characteristic BKN 1P D40A

Electrical installation protection with circuit breaker BKN 1P D40A

This single-pole circuit breaker from the BKN series, with a rated current of 40A and characteristic D, is a reliable safety element in any electrical installation. Designed to protect circuits against overloads and short circuits, it ensures safe use and minimizes the risk of failure. Characteristic D means that this circuit breaker is intended for circuits with high inrush currents, e.g. powering devices with electric motors or transformers.

Characteristics and application

The BKN 1P D40A circuit breaker is distinguished by its high short-circuit breaking capacity – as much as 6kA. This means that in the event of a short circuit, the circuit breaker will quickly and effectively disconnect the circuit, protecting wires and connected devices from damage. This is particularly important in installations exposed to frequent voltage fluctuations or connecting devices generating high inrush currents during start-up.

• Rated current: 40A – ideal for protecting circuits with medium power consumption.
• Characteristic D: provides delayed operation during short-term overloads, allowing for trouble-free starting of devices with motors or transformers.
• Short-circuit breaking capacity: 6kA – guarantees effective protection in the event of a short circuit.
• Single-pole: simple installation and configuration in standard distribution boards.

Installation and reliability

The BKN 1P D40A circuit breaker is compatible with standard TH35 rails, making it easy to install in electrical distribution boards. The solid construction and high-quality materials ensure long-lasting and reliable operation of the device. By choosing this circuit breaker, you are investing in the safety of your electrical installation and peace of mind. It is an essential element for both professional installers and end-users who care about the safety of their home or company.
