Overcurrent circuit breaker, 6kA BKJ63Nd series 1P 50A B characteristic BKJ63Nd 1P B50 BKJ63ND 1P B50

Overcurrent circuit breaker BKJ63Nd 1P 50A is a protective element for electrical installations against overloads and short circuits. The device, manufactured by LS Electric (formerly LG), is designed for mounting on a DIN rail and provides effective protection in circuits with a voltage of up to 400V AC. The B characteristic makes this circuit breaker particularly recommended for protecting circuits with a resistive nature or with a small inrush current, such as lighting or sockets.

This single-pole circuit breaker with a rated current of 50A has a short-circuit breaking capacity of 6kA, which guarantees its reliable operation in emergency situations. Compact dimensions (68x81x18mm) facilitate installation even in tight switchboards. Made of high-quality materials, it meets the requirements of IEC 60898-1 and IEC 60947-2 standards, which confirms its safety and compliance with European standards.

• Overload and short circuit protection: Ensures the safety of the installation and connected devices.
• B characteristic: Ideal for circuits with low inrush current – protects against damage caused by short-term voltage surges.
• 6kA breaking capacity: Guarantees quick and effective disconnection of the circuit in the event of a short circuit.
• DIN rail mounting: Enables easy and quick installation in standard switchboards.
• Compact dimensions: Allow installation in limited space.
• IEC standards compliance: Confirms the safety and high quality of the product.

BKJ63Nd series circuit breakers are widely used in building installations, both residential and commercial. Due to their reliability and compact size, they are also used to protect inverters and other electronic devices sensitive to overvoltage. The possibility of using different characteristics (B, C, D) allows the circuit breaker to be adapted to the specific requirements of a given circuit. This makes it a universal solution for professionals and end-users looking for a solid and safe protection of the electrical installation.
