Overcurrent circuit breaker, 6kA BKJ63Nd series 4P 16A characteristic C BKJ63Nd 4P C16 BKJ63ND 4P C16

Overcurrent circuit breaker BKJ63Nd is a safety element protecting electrical installations against the effects of overloads and short circuits. Model 4P with a rated current of 16A and characteristic C provides reliable protection in electrical circuits. Designed for mounting on a 35mm DIN rail, it is compatible with most standard distribution boards.

Characteristics and application

BKJ63Nd series circuit breakers, including the BKJ63Nd 4P C16 model, are universal devices used in both domestic and industrial installations. Characteristic C means that the circuit breaker reacts with a slight delay to short-term current surges – which is particularly important when protecting circuits with receivers with high inrush current, e.g. electric motors. This ensures stable operation of the installation without unnecessary tripping. The rated current of 16A makes it ideal for protecting lighting circuits, socket outlets or electrical devices with moderate power consumption.

Construction and parameters

The BKJ63Nd circuit breaker is characterized by a solid construction and high quality workmanship. It has a short-circuit breaking capacity of up to 6kA, which guarantees effective protection in the event of serious disturbances in the network. Compliance with IEC 60898-1 and IEC 60947-2 standards confirms its safety and reliability. The width of the circuit breaker is 17.8mm per pole, which allows for optimal use of space in the distribution board. The possibility of connecting wires using lugs or screws provides flexibility during installation. The ambient operating temperature is in the range of -5°C to +40°C.

• Short-circuit breaking capacity: 6kA – high value guaranteeing effective protection against the effects of short circuits.
• Characteristic C: delayed reaction to short-term overloads, ideal for receivers with high inrush current (e.g. motors).
• Rated current: 16A – suitable for circuits with moderate power consumption (lighting, sockets).
• Number of poles: 4P – designed to protect multi-phase circuits or those requiring separation of all phase and neutral conductors.
• Mounting: 35mm DIN rail – standard mounting for easy installation and replacement of the circuit breaker.
• Standards: IEC 60898-1 / IEC 60947-2 – confirmation of compliance with European safety and quality standards.
