Overcurrent circuit breaker, 6kA BKJ63Nd series 2P 6A characteristic D BKJ63Nd 2P D6 BKJ63ND 2P D6

Overcurrent circuit breakers of the BKJ63Nd series – reliable installation protection

The BKJ63Nd 2P 6A circuit breaker with D characteristic is a key element of electrical protection, designed to protect circuits against overloads and short circuits. It is ideally suited for both home installations and more demanding industrial environments. The two-pole design provides comprehensive protection, and the rated current of 6A is suitable for many typical loads.

Characteristics and application

The BKJ63Nd series circuit breakers are characterized by high reliability and durability. The D characteristic means that the breaker has a delayed response to overloads, allowing for trouble-free starting of devices with high current draw, such as motors or transformers. This avoids unnecessary tripping of the circuit during short-term current surges. DIN 35mm rail mounting simplifies and speeds up installation.

• Wide range of applications: ideal for protecting lighting, socket and electrical appliance circuits in residential, commercial and industrial buildings.
• D characteristic: provides a delayed response to overloads, which is particularly important for devices with motors or transformers.
• Two-pole design (2P): ensures disconnection of both phase and neutral, increasing safety.
• Rated current 6A: matched to protect typical loads in electrical installations.
• Short-circuit breaking capacity 6kA: guarantees effective circuit interruption in the event of a short circuit.
• DIN rail mounting: facilitates quick and convenient mounting in the distribution board.
• Possibility of connecting wires with a cross-section of up to 25mm²: provides flexibility in choosing power cables.

Construction and parameters

The BKJ63Nd circuit breaker is made of high-quality materials, which guarantees its long-lasting and trouble-free operation. It has a visual indication of contact status ("on/off"), which facilitates diagnostics and control of the circuit status. Compliance with IEC 60898-1 and IEC 60947-2 standards confirms its safety and reliability. The width of the circuit breaker is 17.8 mm per pole, allowing for efficient use of space in the distribution board. The device operates at temperatures from -5°C to +40°C.
