Overcurrent circuit breaker, 6kA BKJ63Nd series 2P 2A characteristic D BKJ63Nd 2P D2 BKJ63ND 2P D2

Overcurrent circuit breaker BKJ63Nd – reliable installation protection

This two-pole overcurrent circuit breaker from the BKJ63Nd series by LS Electric, with a rated current of 2A and D characteristic, is a key element ensuring safety in electrical installations. Designed to protect against overloads and short circuits, it performs well both in residential and demanding industrial conditions. Its compact dimensions (17.8mm per pole) facilitate mounting on a standard 35mm DIN rail.

Characteristics and application

Circuit breakers with D characteristics are characterized by a delayed response time to overloads, making them ideal for protecting circuits with receivers with high inrush current – such as motors, transformers or power supplies. This avoids unnecessary tripping of the circuit breaker during device startup. This ensures continuity of power supply and minimizes the risk of downtime. This circuit breaker meets the requirements of IEC 60898-1 and IEC 60947-2 standards, which guarantees its high quality and reliability.

Construction and parameters

The BKJ63Nd 2P D2 circuit breaker has screw terminals allowing the connection of wires with a cross-section from 1 to 25 mm². Its housing made of high-quality materials ensures durability and resistance to mechanical damage. Suitable for operation at temperatures from -5°C to 40°C. Provides effective protection against short-circuit currents up to 6kA (at 240/415VAC). Additionally equipped with a contact position indicator, which allows for a quick visual assessment of the circuit breaker status. The electrical endurance of the circuit breaker is as high as 10,000 operating cycles, which confirms its long-term reliability.
