Overcurrent switch, 6kA BKJ63Nd series 3P 4A characteristic B BKJ63Nd 3P B4 BKJ63ND 3P B4

Overcurrent circuit breaker BKJ63Nd 3P 4A is a reliable safety element protecting electrical installations from the effects of overloads and short circuits. Designed for use in both residential and industrial buildings, it provides effective protection for electrical circuits. The three-pole design makes it ideal for protecting three-phase installations.

This circuit breaker is characterized by a B characteristic, which means it is particularly well suited for protecting circuits with inrush loads, such as electric motors or transformers. The B characteristic allows it to react more slowly to short current surges, so it tolerates starting devices with a motor well. The rated current of 4A makes it suitable for protecting circuits with lower power consumption. The short-circuit strength of 6kA guarantees its proper operation even in the event of serious disturbances in the network.

The circuit breaker is mounted on a standard DIN rail with a width of 3 modules, which facilitates its installation and integration with the existing electrical infrastructure. It meets the requirements of IEC60898 standard, which confirms its compliance with applicable safety standards. The IP20 degree of protection provides protection against accidental contact, but does not protect against the effects of water.

• Wide range of applications: ideal for installations in residential, commercial and industrial buildings.
• Overload and short circuit protection: protects the electrical installation from damage caused by excessive load or short circuit.
• B characteristic: provides optimal protection for circuits with inrush loads.
• High short-circuit strength (6kA): guarantees reliable operation in the event of short-circuit currents.
• Easy installation: thanks to the standard mounting on a DIN rail.
• Compliance with standards: meets the requirements of IEC60898 standard, ensuring safety of use.

The BKJ63Nd 3P B4A circuit breaker is a solid and reliable solution for anyone who cares about the safety of their electrical installation. Its compact dimensions (68x81x53.4mm) allow it to be easily placed in a distribution box, and the high quality of workmanship guarantees long-lasting and trouble-free operation. It is an essential element in any modern power system – both for professionals involved in electrical installations and for end-users looking for effective protection of their devices and homes.
