Overcurrent circuit breaker, 6kA BKJ63Nd series 4P 1A B characteristic BKJ63Nd 4P B1 BKJ63ND 4P B1

Overcurrent circuit breaker BKJ63Nd 4P 1A with B characteristic is an element used to protect electrical installations from the effects of overloads and short circuits. It is a four-pole device, which means it protects the entire circuit, including the neutral conductor. Designed to operate in AC and DC networks, it provides reliable operation in a wide range of ambient temperatures.

This circuit breaker, like the entire BKJ63Nd series, is characterized by high breaking capacity (6kA) and complies with IEC 60898-1 and IEC 60947-2 standards. Mounting is done on a standard 35mm DIN rail, which facilitates installation and replacement. The design of the circuit breaker allows for connection of conductors using lugs, ensuring a secure and durable connection.

Characteristic B means that the circuit breaker reacts quickly to an increase in short-circuit current, but is more tolerant to short-term current surges during the start-up of high-power devices – which is particularly important in the case of electric motors or transformers. This minimizes the risk of unnecessary tripping of the circuit during normal operation. The use of characteristic B in the device makes it ideal for circuits with devices generating short current surges at start-up.

• Wide range of applications: ideal for installations in residential, commercial and industrial buildings.
• High reliability: provides effective protection against overloads and short circuits, minimizing the risk of damage to installations and equipment.
• Easy installation: thanks to standard dimensions and the possibility of mounting on a 35mm DIN rail, installation is quick and simple.
• Safety: compliance with IEC 60898-1 and IEC 60947-2 standards guarantees a high level of safety.
• Durable construction: made of high-quality materials resistant to environmental conditions.
• Versatility: suitable for protecting various types of electrical circuits.

BKJ63Nd series circuit breakers are designed to provide long-term and trouble-free operation. Their solid construction and high quality of workmanship guarantee reliable protection of the electrical installation for many years of use. In addition, the possibility of using various accessories (AX, AL, SHT, OVT, UVT) allows you to adapt the circuit breaker to individual user needs.
