Overcurrent circuit breaker, 6kA BKJ63Nd series 4P 1A characteristic C BKJ63Nd 4P C1 BKJ63ND 4P C1

Overcurrent circuit breaker BKJ63Nd 4P 1A with characteristic C is a reliable safety element for electrical installations. Designed for both domestic and industrial applications, it provides effective protection against overloads and short circuits. This four-pole circuit breaker, with a rated current of 1A, is characterized by high efficiency and durability.

Protection and Application

BKJ63Nd series circuit breakers, including the BKJ63Nd 4P C1 model, are designed to protect circuits from the effects of overloads and short circuits. Characteristic C means that the circuit breaker reacts to currents 5 to 10 times higher than the rated current, making it an ideal solution for circuits with loads generating high inrush currents during start-up – such as electric motors or transformers. The use of a four-pole circuit breaker allows for the protection of the entire circuit, including the phase and neutral lines.

Construction and Parameters

The BKJ63Nd 4P C1 circuit breaker is designed for mounting on a 35mm DIN rail. Its compact dimensions make installation easy even in limited spaces. The circuit breaker has a short-circuit breaking capacity of up to 6kA at 415VAC, which guarantees the safety of the installation in the event of serious disturbances. The width of the circuit breaker is 17.8mm per pole, allowing for efficient use of space in the switchgear cabinet. The ambient operating temperature is in the range of -5°C to +40°C.
