Overcurrent circuit breaker, 6kA BKJ63Nd series 4P 6A characteristic C BKJ63Nd 4P C6 BKJ63ND 4P C6

Overcurrent circuit breaker BKJ63Nd is a reliable safety element protecting electrical installations from the effects of overloads and short circuits. Its four-pole design combined with characteristic C makes it an ideal solution for both home and commercial installations. Designed for operation in AC and DC circuits, it provides effective protection for devices and wires.

Characteristics and application

The BKJ63Nd circuit breaker with characteristic C is characterized by a delayed response time to short-term overloads. This is particularly important in circuits with receivers with high starting current, such as motors or transformers. This avoids unnecessary tripping of the circuit during normal operation of the devices. It can be used to protect lighting, socket outlets, and circuits powering electrical devices.

Construction and mounting

The circuit breaker is designed for mounting on a standard 35mm DIN rail. Its compact dimensions (17.8mm per pole) allow for efficient use of space in the distribution board. The ability to connect wires with a cross-section of up to 25mm² provides flexibility in choosing the appropriate cables. Made of high-quality materials, it guarantees durability and reliable operation for a long time. Compliance with IEC 60898-1 and IEC 60947-2 confirms its safety and compliance with applicable standards.

The BKJ63Nd circuit breaker is characterized by a rated current of 6A, a four-pole design and characteristic C, providing a delayed response to short-term overloads. Its breaking capacity is 6kA, and the universal rated voltage is 240/415VAC (AC) and 48VDC (DC). Operation in a wide temperature range from -5°C to +40°C guarantees reliable operation in various environmental conditions. Mounting is done on a standard 35mm DIN rail, and the ability to connect wires with a cross-section of up to 25mm² provides flexibility in choosing the appropriate cables.
