Overcurrent circuit breaker, 6kA BKJ63Nd series 4P 2A characteristic C BKJ63Nd 4P C2 BKJ63ND 4P C2

Overcurrent circuit breakers BKJ63Nd – reliable installation protection

This four-pole BKJ63Nd overcurrent circuit breaker with a rated current of 2A and C characteristic is a key protective element in every electrical installation. It provides effective protection against overloads and short circuits, protecting both devices and wires. It is a universal solution, finding application in residential construction, industry and commercial facilities.

Characteristics and application

BKJ63Nd series circuit breakers are designed for mounting on a 35mm DIN rail. Their compact dimensions (17.8mm per pole) allow for efficient use of space in the distribution board. Thanks to the possibility of connecting wires with a cross-section of up to 25mm², the circuit breaker is compatible with various types of installations. Characteristic C means that the circuit breaker reacts to short-circuit currents in the range of 5 to 10 times the rated current, making it ideal for protecting circuits with devices generating surge currents during start-up (e.g., motors). This circuit breaker complies with IEC 60898-1 and IEC 60947-2 standards, guaranteeing its safety and reliability.

Construction and design features

The BKJ63Nd circuit breaker is distinguished by its solid construction and high quality of workmanship. It has universal connection terminals – both screw and lug – which facilitates installation and provides flexibility in the selection of wires. The rated operating voltage is 240/415VAC (1P) or 415VAC (2-4P), making it suitable for most standard electrical installations. The circuit breaker is designed to operate in temperatures from -5°C to +40°C, ensuring its reliability in various environmental conditions. Additionally, the possibility of mounting additional modules (e.g., auxiliary switches) expands the functionality of the circuit breaker, adapting it to the specific needs of the installation. The use of high-quality materials ensures long-term operation of the device – the electrical endurance is confirmed by 10,000 switching cycles.
