Overcurrent circuit breaker, 6kA BKJ63Nd series 2P 3A characteristic C BKJ63Nd 2P C3 BKJ63ND 2P C3

Overcurrent circuit breaker BKJ63Nd 2P 3A is a component used to protect electrical installations from the effects of overloads and short circuits. It is a key component ensuring safe operation in residential, commercial buildings and in industry. This device, thanks to its C characteristic, is perfect for circuits with receivers generating inrush currents during start-up – such as motors or transformers.

The breaker's construction is based on LS Electric technology, guaranteeing reliability and long life. Mounting is done on a standard 35mm DIN rail, which facilitates installation and replacement. The two-pole design (2P) allows protection of two phase conductors, providing complete circuit protection. The rated breaking current (6kA) means that the device is able to interrupt a short-circuit current of up to 6 kA, minimizing the risk of damage and fire.

The C characteristic of the breaker means that its operation is delayed in relation to sudden current surges, typical for starting devices with induction motors or transformers. This avoids unnecessary tripping of the circuit during normal operation of these devices. This breaker meets the requirements of IEC 60898-1 and IEC 60947-2 standards, confirming its compliance with European safety standards. The possibility of connecting wires with a cross-section of up to 25mm² provides flexibility in choosing the appropriate cables for the protected circuit. Additionally, the compact dimensions (17.8mm wide per pole) allow for efficient use of space in the switchgear.
