Overcurrent circuit breaker, 6kA BKJ63Nd series 1P 32A B characteristic BKJ63Nd 1P B32 BKJ63ND 1P B32

Overcurrent circuit breaker BKJ63Nd is a safety element protecting electrical installations against overloads and short circuits. Designed for mounting on a 35mm DIN rail, it is a reliable solution for both professional installers and end users. This model, with a rated current of 32A and characteristic B, provides effective protection of electrical circuits in residential and commercial buildings.

Characteristics and application

The BKJ63Nd circuit breaker from the BKJ63N series is characterized by high reliability and durability. Characteristic B means that the circuit breaker reacts quickly to an increase in short-circuit current, but is more tolerant to short-term inrush currents, making it ideal for protecting circuits with devices with high power consumption during startup – e.g. motors. Use in electrical installations allows for safe operation of devices and minimizes the risk of failure due to overload or short circuit. This circuit breaker meets the requirements of IEC 60898-1 and IEC 60947-2 standards, guaranteeing its compliance with applicable safety standards.

Construction and parameters

The construction of the circuit breaker is based on solid materials, ensuring long-lasting and trouble-free operation. The circuit breaker has screw or lug terminals (depending on the version), allowing easy connection of wires with a cross-section of up to 25mm². The width of a single pole is 17.8mm, which allows for efficient use of space in the distribution box. The circuit breaker is adapted to work in temperatures from -5°C to +40°C, making it a universal solution for various environmental conditions. The rated impulse voltage is 4kV, and the insulation – 500V. This circuit breaker has a short-circuit breaking capacity of up to 6kA at a voltage of 240/415VAC.
