Overcurrent circuit breaker, 6kA BKJ63Nd series 2P 63A characteristic D BKJ63Nd 2P D63 BKJ63ND 2P D63

Overcurrent circuit breaker BKJ63Nd 2P 63A is a reliable safety element protecting electrical installations against overloads and short circuits. Designed for both domestic and professional applications, it provides effective protection of electrical circuits. The two-pole (2P) design allows for the protection of two phase conductors, increasing the safety of the entire system.

Characteristics and application

The circuit breaker from the BKJ63Nd series is characterized by a D characteristic, which means that it can withstand short-term overloads, such as those occurring during the starting of electric motors or devices with heating elements. This minimizes the risk of unnecessary circuit tripping. The rated current of 63A makes it suitable for protecting circuits with higher power consumption. This is particularly important in installations where many devices are connected simultaneously.

BKJ63Nd circuit breakers are mounted on a 35mm DIN rail, which simplifies and speeds up their installation in electrical distribution boards. The width of one pole is 17.8mm, which allows for efficient use of space in the distribution cabinet. The use of high-quality materials guarantees long life and reliable operation of the device – it withstands up to 10,000 operating cycles.

Safety and compliance with standards

This circuit breaker meets the requirements of IEC 60898-1 and IEC 60947-2 standards, confirming its safety and compliance with applicable standards. It provides effective protection against the effects of overloads and short circuits, protecting both the electrical installation and the devices connected to it. Adapted to operate in standard environmental conditions – its operation is not disturbed by typical conditions prevailing in technical rooms or residential buildings.
