Overcurrent circuit breaker, 6kA series BKN 1P 6A characteristic D BKN 1P D6A

6kA Overcurrent Circuit Breaker BKN series 1P 6A D characteristic

This single-pole overcurrent circuit breaker from the BKN series, with a rated current of 6A and D characteristic, is a reliable protection for electrical installations. Designed to protect circuits against overload and short circuit, it performs well in various applications – both in home and industrial installations. Its compact size facilitates mounting in switchboards, and the high quality of workmanship guarantees long-lasting and trouble-free operation.

Protection and functionality

The BKN 1P D6A circuit breaker is characterized by a high short-circuit breaking capacity – up to 6kA. This means that it effectively breaks the circuit in the event of a serious short circuit, minimizing the risk of equipment damage and fire. The D characteristic provides a delayed tripping, which is particularly important for loads with high inrush current – such as electric motors or transformers. This ensures that the circuit breaker does not trip unnecessarily during short-term current surges associated with device start-up.

Installation and compatibility

The BKN series circuit breaker is compatible with a wide range of additional accessories, allowing it to be adapted to individual installation needs. The ability to mount additional elements increases the functionality and flexibility of the protection system. The circuit breaker is designed to operate in circuits with a rated voltage of 230/400V AC and 72V DC. The cross-section of the conductors connected to the circuit breaker can range from 1 to 25 mm².
