Overcurrent circuit breaker, 6kA BKJ63Nd series 1P 6A characteristic D BKJ63Nd 1P D6 BKJ63ND 1P D6

Overcurrent circuit breakers of the BKJ63Nd series – reliable installation protection

The BKJ63Nd overcurrent circuit breaker is a protective element designed to protect electrical circuits against the effects of overloads and short circuits. This device, characterized by its high efficiency and durability, finds application both in home installations and in industrial facilities. The BKJ63Nd 1P 6A model with characteristic D provides optimal protection for circuits with receivers with high starting current, such as motors or transformers.

Characteristics and application

BKJ63Nd circuit breakers are distinguished by their compact design and easy mounting on a 35mm DIN rail. This makes installation quick and convenient. Characteristic D means that the circuit breaker reacts to short-circuit currents with a higher value than models with characteristic B or C, which minimizes the risk of unnecessary tripping of the circuit when starting devices with high power consumption. This is particularly important in industrial applications and in buildings with a large number of inductive loads. The use of this type of circuit breaker allows you to protect the electrical installation from damage caused by overloads or short circuits, and thus ensures safety of use and minimizes the risk of failure.

Construction and parameters

The BKJ63Nd 1P 6A circuit breaker has been designed for long-term and reliable operation. It has high resistance to atmospheric conditions and mechanical damage. The rated breaking current is 6kA at 240/415VAC, which guarantees effective protection in the event of a short circuit. The device meets the requirements of IEC 60898-1 and IEC 60947-2 standards, which confirms its safety and compliance with applicable standards. Made of high-quality materials, it ensures stable operation for a long time. Additionally, compact dimensions (68x81x18 mm for the 1-pole version) make it easy to install even in tight switchboards.
