Overcurrent circuit breaker, 6kA series BKN 1P 63A characteristic D BKN 1P D63A

Overcurrent circuit breakers of the BKN series – reliable installation protection

The BKN series installation circuit breaker is a compact and efficient device designed to protect electrical circuits against overloads and short circuits. The BKN 1P D63A model, with a rated current of 63A, is characterized by its high efficiency and durability, making it an ideal solution for both domestic and industrial installations. The thermomagnetic circuit breaker design ensures a quick and precise response in the event of a dangerous situation.

Characteristics and application

The BKN 1P D63A circuit breaker has a D characteristic, which means it is designed to protect circuits with receivers with high inrush current – such as motors, transformers or heating devices. The D characteristic allows it to react more slowly to short current surges, so it tolerates starting devices with a motor well. This ensures reliable protection of the installation without unnecessary tripping of the circuit during normal operation. Mounting on a 35mm DIN rail is quick and intuitive, making installation and servicing easier.

Key features and benefits

• High breaking capacity: 6kA – guarantees effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage and fire.
• D characteristic: ideal for protecting circuits with inductive receivers with high inrush current.
• Compact dimensions: 17.8mm wide per pole – allows for efficient use of space in the switchboard.
• DIN rail mounting: simplifies and speeds up installation and servicing.
• Durable construction: ensures long-lasting and reliable operation in various environmental conditions.
• Compliance with standards: meets the requirements of IEC 60947-2 standards, confirming its safety and quality.
• Possibility of connecting wires up to 25mm²: provides flexibility in choosing wire cross-sections adapted to the load.

BKN circuit breakers are a proven choice for professionals and users who value the safety and reliability of electrical installations. Protects the circuit against overload and short circuit — like most circuit breakers in this class.
