Overcurrent switch, 6kA BKJ63Nd series 3P 2A characteristic B BKJ63Nd 3P B2 BKJ63ND 3P B2

Overcurrent circuit breaker BKJ63Nd 3P B2 is a three-pole safety element protecting the electrical installation against overloads and short circuits. Designed for mounting on a 35mm DIN rail, it is a reliable solution for both home and commercial installations.

Characteristics and application

The BKJ63Nd series circuit breaker is characterized by a B characteristic, which means it is particularly suitable for protecting circuits with devices with high inrush current – such as electric motors or transformers. This characteristic allows it to react more slowly to short-term current surges, avoiding unnecessary tripping of the circuit during device startup. The rated current of 2A makes this circuit breaker ideal for protecting circuits with lower power consumption, such as lighting or power outlets for electronic devices. The rated short-circuit breaking capacity of 6kA guarantees effective protection in the event of serious disturbances in the installation.

Construction and mounting

The BKJ63Nd circuit breaker has been designed for easy installation and convenient operation. The ability to connect wires with a cross-section of up to 25mm² provides flexibility in choosing wires tailored to specific installation needs. Compact dimensions (17.8mm wide per pole) allow for efficient use of space in the distribution board. Made of high-quality materials, it ensures durability and reliable operation for a long time. Compliance with IEC 60898-1 and IEC 60947-2 standards confirms its safety and compliance with stringent quality standards.
