Overcurrent circuit breaker, 6kA BKJ63Nd series 1P 25A characteristic C BKJ63Nd 1P C25 BKJ63ND 1P C25

Overcurrent circuit breaker BKJ63Nd 1P C25 is a reliable safety element protecting electrical installations from the effects of overloads and short circuits. Designed for mounting on a 35mm DIN rail, it provides effective protection in circuits with a rated current of 25A. The construction of this circuit breaker, based on proven LS Electric technology, guarantees long-term and trouble-free operation.

Characteristics and application

The BKJ63Nd series circuit breaker with C characteristic is ideal for protecting circuits with receivers with moderate inrush currents, such as motors, transformers or heating devices. The C characteristic allows for momentary exceeding of the rated current without unnecessary tripping of the circuit, which is particularly important in the case of devices requiring higher current during start-up. This ensures stable operation of the installation and minimizes the risk of false alarms. This circuit breaker finds application both in domestic and industrial installations, where high reliability and safety are required.

Construction and parameters

The BKJ63Nd circuit breaker is characterized by a compact design with a width of 17.8mm per pole, which allows for efficient use of space in the switchgear cabinet. It has both screw and lug terminals, which facilitates the connection of wires with a cross-section of up to 25mm². Made of high-quality materials, it provides resistance to environmental conditions and long service life – it withstands up to 10,000 electrical operating cycles and 20,000 mechanical cycles. Adapted to operate at temperatures from -5°C to +40°C. Compliance with IEC 60898-1 and IEC 60947-2 standards confirms its safety and quality of workmanship. The circuit breaker has a short-circuit breaking capacity of up to 6kA at 240/415V AC (50/60Hz).

Key product features:

• Short-circuit breaking capacity: 6kA – effectively interrupts the circuit in the event of a short circuit, protecting the installation from damage.
