Overcurrent circuit breaker, 6kA BKJ63Nd series 2P 3A characteristic D BKJ63Nd 2P D3 BKJ63ND 2P D3

Overcurrent circuit breaker BKJ63Nd 2P 3A is an element used to protect electrical installations from the effects of overloads and short circuits. It is a two-pole circuit breaker, which means it protects two independent circuits. The rated current of 3A makes it suitable for protecting circuits with lower current consumption, such as lighting or sockets in residential premises.

This model of circuit breaker is characterized by a D characteristic curve, which means it is designed to protect circuits with receivers generating high inrush currents during start-up – such as electric motors, transformers or switch-mode power supplies. The D characteristic allows it to react more slowly to short current surges, so it tolerates the starting of devices with a motor well. This ensures reliable protection without unnecessary tripping under normal operating conditions.

The BKJ63Nd circuit breaker meets the requirements of IEC 60898-1 and IEC 60947-2 standards, which guarantees its safety and reliability. It has a short-circuit breaking capacity of 6kA, which means it is able to interrupt the flow of short-circuit current with a value of up to 6000 amps. Mounting is done on a standard 35mm DIN rail, which facilitates installation and replacement.

• Overload and short-circuit protection: Protects the circuit from damage caused by excessive current draw or a short circuit – like most circuit breakers in this class.

• D characteristic curve: Ideal for circuits with receivers generating high inrush currents during start-up.

• Short-circuit breaking capacity 6kA: Ensures effective interruption of short-circuit current.

• Mounting on 35mm DIN rail: Facilitates and speeds up installation.

• Two-pole (2P): Protects two independent circuits.

• Rated current 3A: Suitable for protecting circuits with lower current consumption.

• Compliant with IEC 60898-1 and IEC 60947-2 standards: Confirms the safety and quality of the product.

BKJ63Nd series circuit breakers are widely used in electrical installations of residential, commercial and industrial buildings. Thanks to their reliability and effectiveness, they ensure safe and stable operation of the electrical installation. The choice of the D characteristic makes them particularly recommended where there are receivers generating high inrush currents during start-up – such as motors or switch-mode power supplies. Installation is simple and intuitive thanks to the standard mounting on a 35mm DIN rail.
