Overcurrent circuit breaker, 6kA BKJ63Nd series 2P 4A characteristic D BKJ63Nd 2P D4 BKJ63ND 2P D4

Electrical installation protection with BKJ63Nd circuit breaker

This two-pole circuit breaker from the BKJ63Nd series is a reliable protection for electrical circuits. Designed to protect against the effects of overloads and short circuits, it performs well in both domestic and industrial installations. Characteristic D provides a delayed response in the event of short-term current surges, which is particularly important when protecting devices with high starting current – such as motors or transformers.

This circuit breaker is mounted on a standard 35mm DIN rail, which facilitates its installation and replacement. Its compact dimensions (17.8mm per pole) allow for efficient use of space in the switchgear cabinet. The use of high-quality materials in the construction guarantees a long service life and reliable operation, confirmed by a certificate of compliance with IEC 60898-1 and IEC 60947-2 standards.

• Characteristic D: Provides a delayed response, ideal for circuits with devices with high starting current – protects against unnecessary tripping during the start-up of motors or transformers.
• Rated capacity: Suitable for use with wires with a cross-section of up to 25mm², which provides flexibility in choosing wires for specific applications.
• Overload and short-circuit protection: Standard protection offered by this type of circuit breaker – protects the electrical installation from damage caused by malfunctioning devices or failures.
• DIN rail mounting: Enables quick and easy mounting in standard electrical distribution boards.
• High electrical endurance: Withstands 10,000 operating cycles, guaranteeing long-term and trouble-free use.
• Suitable for operation in various conditions: Compliance with IEC standards ensures safe use in various working environments.

The BKJ63Nd 2P 4A circuit breaker is a solid solution for professionals and users who value the safety and reliability of their electrical installation. Its versatility makes it suitable for use in many different facilities – from single-family homes to industrial plants.
