Overcurrent circuit breaker, 6kA BKJ63Nd series 4P 63A characteristic C BKJ63Nd 4P C63 BKJ63ND 4P C63

Overcurrent circuit breaker BKJ63Nd 4P 63A is a reliable safety element protecting electrical installations from the effects of overloads and short circuits. Designed for use in both residential and industrial buildings, it provides effective protection for electrical circuits. The four-pole design allows for the protection of polyphase installations, and the rated current of 63A makes it suitable for protecting circuits with higher power consumption.

Characteristics and application

The BKJ63Nd series circuit breaker is characterized by a C characteristic, which means it has a delayed response to short-term current increases. This is particularly important for circuits powering devices with induction motors or other loads generating high inrush currents – allowing them to start without unnecessarily tripping the circuit breaker. Use in electrical installations guarantees safety and protection against damage caused by failures. These circuit breakers are compatible with 35mm mounting rails, making them easy to install and replace.

Construction and parameters

The BKJ63Nd circuit breaker has been designed with durability and reliability in mind. It has high resistance to environmental conditions, and its housing is made of high-quality materials providing insulation and protection against mechanical damage. The rated short-circuit breaking capacity is 6kA, which guarantees effective disconnection of the circuit in the event of a short circuit. It meets the requirements of IEC 60898-1 and IEC 60947-2 standards, confirming its safety and compliance with applicable standards. Mounting is done using standard tools on a DIN rail, which significantly speeds up the installation process. The connection terminal allows connection of wires using lugs or screws, providing flexibility during installation.
