Overcurrent circuit breaker, 6kA BKJ63Nd series 4P 50A characteristic C BKJ63Nd 4P C50 BKJ63ND 4P C50

Overcurrent switch – reliable protection for electrical installations

This four-pole overcurrent switch from the BKJ63Nd series with a rated current of 50A and C characteristic is a key element ensuring safety in every electrical installation. Designed to protect against overloads and short circuits, it works well both in residential buildings and industrial facilities. Its versatility and high quality workmanship guarantee long-lasting and trouble-free operation.

Design and application

The BKJ63Nd switch is designed for mounting on a DIN rail, which facilitates its installation and integration with the existing electrical system. The C characteristic means that the switch reacts to overload currents in the range of 5 to 10 times the rated current, making it an ideal solution for circuits with devices generating short-term current surges, e.g. motors. It provides effective protection of circuits against damage caused by overload or short circuit.

Key features and benefits

• High breaking capacity: 6kA – ensures safe disconnection of the circuit in the event of a short circuit, minimizing the risk of damage and fire.
• C characteristic: ideal for protecting circuits with inductive loads (motors, transformers) and lighting. Allows for short-term overloads without unnecessary tripping of the circuit.
• Four-pole construction: allows you to protect the entire circuit (L1, L2, L3, N) with one device, which simplifies installation and increases safety.
• DIN rail mounting: quick and easy mounting in the switchboard saves time and installation costs.
• Wide rated voltage range: 230/400V AC – compatible with most standard electrical installations.
• Protection degree IP20: provides protection against accidental contact and the ingress of solid objects larger than 12mm.
• Durable construction: made of high-quality materials guarantees reliable operation for a long time.
• Compliance with IEC 60898-1 / 60947-2 standards: confirms compliance with strict safety and quality requirements.

BKJ63Nd switches are a proven choice for professionals and demanding end-users who value safety, reliability and ease of use. Thanks to their versatility, they find application in various electrical installations – from domestic to industrial.
