Overcurrent circuit breaker, 6kA BKJ63Nd series 4P 10A characteristic C BKJ63Nd 4P C10 BKJ63ND 4P C10

Overcurrent circuit breaker BKJ63Nd 4P 10A is an element used to protect electrical installations against the effects of overloads and short circuits. It is a key component ensuring the safety of electricity use in both residential and commercial buildings. Made of high-quality materials, it guarantees reliable operation and long service life.

Characteristics and application

The BKJ63Nd series circuit breaker is characterized by a rated current of 10A and a C characteristic. This means that this circuit breaker reacts quickly to short circuits, but is more resistant to short-term overloads than circuit breakers with a B characteristic. Therefore, it is ideal for protecting circuits with receivers generating inrush currents during start-up, such as motors, pumps or refrigeration units. The four-pole design (4P) allows for the protection of the entire circuit, including the neutral conductor, which further increases the level of safety.

Construction and assembly

The circuit breaker is mounted on a standard 35mm DIN rail, which facilitates its installation and replacement. Compact dimensions allow for efficient use of space in the distribution board. The use of lug terminals ensures a secure and durable connection of conductors with a cross-section of up to 25mm². BKJ63Nd circuit breakers have been designed with ease of assembly and intuitive operation in mind, which will be appreciated by both professional installers and people performing electrical work independently.
