Overcurrent circuit breaker, 6kA BKJ63Nd series 3P 10A characteristic C BKJ63Nd 3P C10 BKJ63ND 3P C10

Overcurrent circuit breaker from the BKJ63Nd series is a safety element protecting the electrical installation against overloads and short circuits. Designed for mounting on a 35mm DIN rail, it provides reliable protection in circuits with a rated current of 10A. The three-pole (3P) design makes it ideal for protecting polyphase electrical installations.

Characteristics and application

The BKJ63Nd circuit breaker is characterized by a C characteristic, which means it allows for short-term current overloads that occur, for example, during the starting of electric motors or other devices with high power consumption. This minimizes the risk of unnecessary tripping of the circuit. Use in building installations, both in apartments and commercial facilities, guarantees safety and protection against damage. This is particularly important in places where devices generating inrush currents during start-up are present.

Construction and parameters

The circuit breaker has been designed with durability and reliability in mind. Its housing is made of high-quality materials resistant to mechanical damage and the influence of atmospheric conditions (IP20). The rated short-circuit breaking capacity is 6kA at 240/415V AC, which ensures effective protection in the event of a short circuit. The possibility of mounting on a DIN rail facilitates and speeds up installation. The screw-lug terminal allows connection of conductors with a cross-section of up to 25mm². The circuit breaker meets the requirements of IEC 60898-1 and IEC 60947-2 standards, confirming its compliance with European safety standards.
