Overcurrent circuit breaker, 6kA series BKN 3P 32A characteristic D BKN 3P D32A

Electrical installation protection with BKN 3P D32A circuit breaker

The BKN 3P series overcurrent circuit breaker with a rated current of 32A and D characteristic is a reliable element protecting electrical installations from the effects of overloads and short circuits. Designed for use in circuits requiring a delayed response to short-term current increases, it is ideal for protecting devices with high inrush currents, such as motors or transformers. The three-pole design provides comprehensive protection in three-phase systems.

Characteristics and application

The D characteristic of the circuit breaker means that its operating time is delayed compared to circuit breakers with B, C characteristics. This allows for trouble-free starting of devices generating high surge currents without unnecessary tripping of the circuit. The rated current of 32A makes it suitable for protecting circuits with medium loads. This circuit breaker is used in building installations - both residential and commercial - as well as in industrial facilities.

Solid construction and parameters

The BKN 3P D32A circuit breaker is characterized by high efficiency due to its short-circuit breaking capacity of up to 6kA. DIN rail mounting simplifies and speeds up installation. The IP20 degree of protection provides protection against accidental contact, but does not protect against the effects of water or dust - remember to provide appropriate working conditions (ambient temperature from -5°C to 40°C). The possibility of connecting wires with a cross-section from 1mm² to 25mm² provides flexibility in choosing the appropriate cables. Additionally, contact status visualization allows for quick identification of any problems with the circuit breaker.
