Overcurrent circuit breaker, 6kA BKJ63Nd series 2P 25A characteristic C BKJ63Nd 2P C25 BKJ63ND 2P C25

Electrical installation protection with BKJ63Nd circuit breaker

This two-pole circuit breaker from the BKJ63Nd series, with a rated current of 25A and C characteristic, is a reliable protection for your electrical installation. Designed to protect against the effects of overloads and short circuits, it ensures safe operation and long-term stability. It is a key element of every installation, both in residential and commercial buildings.

Construction and application

The BKJ63Nd circuit breaker is designed for mounting on a 35mm DIN rail. Its compact dimensions (17.8mm wide per pole) allow for efficient use of space in the distribution board. Thanks to the universal screw and lug terminals, connecting cables with a cross-section of up to 25mm² is quick and convenient. This circuit breaker is used in lighting circuits, socket circuits, and for protecting electrical devices with moderate power consumption. The C characteristic makes it ideal for circuits with devices generating inrush currents during start-up – e.g. motors or transformers.

Key features and benefits

• High breaking capacity: Rated breaking capacity of 6kA at 240/415VAC guarantees effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage and fire.
• C characteristic: Provides a delayed response to short-term overloads, which helps avoid unnecessary tripping caused, for example, by starting motors or transformers.
• Universal terminals: The ability to connect cables using screw or lug terminals increases installation flexibility and simplifies mounting.
• Durable construction: The circuit breaker is made of high-quality materials, which ensures its reliability and long service life – it withstands 10,000 electrical operating cycles and 20,000 mechanical cycles.
• Compliance with standards: Meets the requirements of IEC 60898-1 and IEC 60947-2 standards, which confirms its safety and quality.
• Compact dimensions: A width of only 17.8mm per pole allows for optimal use of space in the distribution board.

BKJ63Nd circuit breakers are a proven choice for professionals and users who value the safety and reliability of their electrical installation.
