Overcurrent circuit breaker, 6kA BKJ63Nd series 1P 25A B characteristic BKJ63Nd 1P B25 BKJ63ND 1P B25

Overcurrent circuit breaker BKJ63Nd 1P 25A is an electrical installation protection element, designed to protect circuits against overload and short circuit. It is a single-pole circuit breaker, meaning it is used to protect a single phase wire. Its B characteristic ensures a quick response to current increase, which is particularly important for resistive loads and lighting.

This LS Electric model from the BKJ63Nd series is distinguished by its compact dimensions and easy mounting on a DIN rail. It is designed for operation in installations with a voltage of 230/400V AC and has a short-circuit breaking capacity of up to 6kA. This ensures effective protection for both home and commercial installations. This circuit breaker is compatible with wires with a cross-section from 1mm² to 25mm², providing flexibility in choosing the appropriate wire for a given application.

• Quick response: B characteristic ensures fast operation in case of overload or short circuit, minimizing the risk of damage to equipment and installation.
• Short-circuit breaking capacity: 6kA guarantees effective circuit interruption in the event of a short circuit, protecting against serious failures.
• DIN rail mounting: Allows for easy and quick installation in a distribution board.
• Wide range of applications: Suitable for protecting lighting circuits, socket circuits and other electrical devices of a resistive nature.
• Operating indicator: Has a visual indicator of contact position, making it easier to identify the status of the circuit breaker.
• Operating temperature: Trouble-free operation in the temperature range from -5°C to +40°C makes it suitable for most standard installation conditions.

BKJ63Nd circuit breakers are characterized by high reliability and long mechanical (20,000 cycles) and electrical (10,000 cycles) life. They meet the standards IEC 60898-1 and IEC 60947-2, which confirms their safety and compliance with applicable standards. The construction with screw or lug terminals ensures a secure connection with electrical wires. The width of the circuit breaker is 17.8 mm per pole, allowing for efficient use of space in the distribution board.
