Overcurrent circuit breaker, 6kA BKJ63Nd series 1P 16A characteristic C BKJ63Nd 1P C16 BKJ63ND 1P C16

Circuit breakers of the BKJ63Nd series are a key element in protecting electrical installations, both in residential and industrial buildings. This single-pole breaker with a rated current of 16A and C characteristic provides effective protection against overloads and short circuits.

Application and functions

BKJ63Nd circuit breakers, replacing the BKN series with improved technical parameters, are designed to protect electrical circuits from the effects of currents exceeding permissible standards. Characteristic C means that the breaker reacts to short-circuit currents in the range of 5 to 10 times the rated current, making it an ideal solution for circuits with devices generating short-term current surges – such as motors. This minimizes the risk of unnecessary tripping of the circuit when starting devices. Additionally, the use of a separate terminal for the wire and the busbar facilitates installation and ensures a secure connection.

Construction and parameters

The BKJ63Nd 1P C16 circuit breaker is designed for mounting on a 35mm DIN rail. It has a protection degree of IP20, which means protection against touching with a finger and solid objects larger than 12.5 mm. Its construction ensures high reliability and long life – it withstands 10,000 electrical cycles and 20,000 mechanical cycles. Made of high-quality materials, it meets the standards of IEC 60898-1 and IEC 60947-2, guaranteeing safety of use. Adapted to operate at ambient temperatures from -5°C to +40°C.
