Overcurrent circuit breaker, 6kA BKJ63Nd series 2P 4A B characteristic BKJ63Nd 2P B4 BKJ63ND 2P B4

Protection of electrical installations and devices

Overcurrent circuit breaker BKJ63Nd 2P 4A with B characteristic is a reliable safety element in every electrical installation. Designed to protect against the effects of overloads and short circuits, it ensures safe and stable operation of circuits in residential, commercial and industrial buildings. The two-pole design effectively protects two independent circuits.

Characteristics and application

B characteristic means that the circuit breaker reacts quickly to current increase, but is more resistant to short-term surges than models with C characteristic. This makes it ideal for protecting lighting circuits, socket outlets and other devices with low starting impedance. The breaking capacity of 6kA guarantees effective disconnection of the circuit in the event of a serious failure. Mounting on a standard 35mm DIN rail facilitates installation and replacement.

Construction and product features

The BKJ63Nd circuit breaker is designed for durability and reliability. Made of high-quality materials, it provides long-lasting protection without the need for frequent replacement. Compliance with IEC 60898-1 and IEC 60947-2 standards confirms its safety and compliance with applicable standards. The possibility of connecting wires with a cross-section of up to 25mm² provides flexibility during installation. It is worth noting the compact dimensions - the width of one pole is only 17.8mm, which allows for efficient use of space in the distribution board.
