Overcurrent circuit breaker, 6kA BKJ63Nd series 3P 2A characteristic D BKJ63Nd 3P D2 BKJ63ND 3P D2

Overcurrent circuit breaker BKJ63Nd 3P 2A with D characteristic is a three-pole protection device designed to protect electrical installations against overloads and short circuits. It provides reliable operation in AC and DC circuits, and its compact design facilitates mounting on a standard 35mm DIN rail.

This circuit breaker, thanks to its D characteristic, is particularly recommended for protecting circuits with devices with high inrush current – such as motors, transformers or impulse power supplies. The D characteristic allows for momentary exceeding of the rated current without unnecessary tripping, which minimizes the risk of false alarms and downtime.

Construction and mounting:

The BKJ63Nd circuit breaker is distinguished by its solid construction and high quality of workmanship. It has universal terminals – both screw and lug – allowing connection of wires with a cross-section of up to 25mm². Mounting is done by easily snapping onto the DIN rail, which significantly speeds up the installation process. The width of the circuit breaker is 17.8mm per pole, which allows for efficient use of space in the switchgear cabinet.

Application and compliance with standards:

The circuit breaker meets the requirements of IEC 60898-1 and IEC 60947-2 standards, which guarantees its safety and reliability. It can be used in domestic, commercial and industrial installations. Its high electrical endurance (10,000 cycles) ensures long-term and trouble-free operation. Application in circuits with AC 240V (up to 6A) and DC 48V (up to 2A) voltage makes it a versatile solution for various applications.

Key features:

• D characteristic: Ideal for protecting circuits with high inrush current, minimizes the risk of unnecessary tripping.
• Rated capacity: 6kA at AC 240/415V – effective protection against the effects of short circuits.
• Universal terminals: Screw and lug terminals allow flexible connection of wires with a cross-section of up to 25mm².
• DIN rail mounting: Quick and easy mounting on a standard 35mm DIN rail.
• Compliance with standards: Meets the requirements of IEC 60898-1 and IEC 60947-2 – guarantee of safety and reliability.
• Three-pole design (3P): Provides comprehensive protection for three-phase electrical circuits.
