Overcurrent circuit breaker, 6kA BKJ63Nd series 3P 20A B characteristic BKJ63Nd 3P B20 BKJ63ND 3P B20

Overcurrent circuit breaker BKJ63Nd 3P B20 is a three-pole safety element protecting the electrical installation against the effects of overloads and short circuits. Designed for use in circuits with a voltage of up to 400V AC, it provides effective protection for devices and cables. It is characterized by high reliability and durability, making it an ideal choice for both professional installers and end users.

This model of circuit breaker, with a rated current of 20A and B characteristic, is designed to protect circuits with moderate inrush currents. Characteristic B means that the circuit breaker reacts quickly to overvoltage, but tolerates short-term current surges, which is particularly important when connecting devices with motors or other elements generating current pulses. The breaking capacity at 6kA guarantees safe disconnection of the circuit in the event of a short circuit.

The construction of the BKJ63Nd circuit breaker allows mounting on a standard 35mm DIN rail. It has universal terminals – both screw and lug – which facilitates the connection of cables with a cross-section of up to 25mm². The circuit breaker meets the requirements of IEC 60898-1 and IEC 60947-2 standards, confirming its compliance with European safety standards. Its solid construction ensures a long electrical life (10,000 cycles) and mechanical life (20,000 cycles).

• Wide range of applications: ideal for protecting lighting circuits, socket outlets and other loads in residential and commercial buildings.
• Universal terminals: possibility of connecting cables with screws or lugs – installation flexibility.
• High breaking capacity: 6kA ensures effective disconnection of the circuit in the event of a short circuit.
• Compliance with standards: meets the requirements of IEC 60898-1 and IEC 60947-2 – guarantee of safety and reliability.
• Durable construction: ensures long electrical and mechanical life of the device.
• Compact dimensions: facilitate mounting in switchboards with limited space.

BKJ63Nd series circuit breakers are characterized by high quality workmanship and precise operation, which translates into safety and comfort of use. These are essential components in any modern electrical installation, providing protection against failures and fire hazards.
