Overcurrent circuit breaker, 6kA BKJ63Nd series 1P 50A characteristic C BKJ63Nd 1P C50 BKJ63ND 1P C50

Electrical installation protection with BKJ63Nd circuit breaker

The BKJ63Nd circuit breaker is a reliable element protecting electrical installations against the effects of overloads and short circuits. Designed for use in circuits with a voltage of 240/415V AC (depending on the number of poles), it provides effective protection in both residential and industrial buildings. This model, with a rated current of 50A and characteristic C, is ideal for circuits with devices generating inrush currents, such as motors or transformers.

Characteristics and application

BKJ63Nd series circuit breakers are characterized by high resistance to mechanical damage and stable operation in a wide temperature range (from -5°C to +40°C). Characteristic C means that the circuit breaker reacts to overload currents in the range of 5 to 10 times the rated current, which helps avoid unnecessary tripping during short-term load surges. This makes it an ideal solution for circuits powering devices with high power consumption during start-up. Mounting is done on a standard 35mm DIN rail, which simplifies and speeds up installation.

Key features and benefits
