Overcurrent circuit breaker, 6kA BKJ63Nd series 3P 16A characteristic D BKJ63Nd 3P D16 BKJ63ND 3P D16

Overcurrent circuit breaker BKJ63Nd 3P 16A is a safety element protecting the electrical installation against overloads and short circuits. It belongs to the BKJ63Nd series from LS Electric, characterized by high reliability and durability. Designed for mounting on a 35mm DIN rail, it provides effective protection in three-phase circuits.

Characteristics and application

This three-pole circuit breaker with a rated current of 16A has a D characteristic, which means a delayed response to current increase. This solution is particularly useful in circuits with receivers with high inrush current, such as electric motors, pumps or power supplies. The D characteristic prevents unnecessary tripping of the breaker during short-term current surges, while ensuring full protection against overloads and short circuits. This breaker is used in building installations (apartments, houses, offices) and in industrial facilities.

Construction and parameters

The BKJ63Nd circuit breaker is made of high-quality materials, guaranteeing its long-lasting and trouble-free operation. It has high resistance to atmospheric and mechanical conditions. The rated short-circuit breaking capacity is 6kA at 240/415VAC, which ensures effective disconnection of the circuit in the event of a short circuit. The breaker meets the requirements of IEC 60898-1 and IEC 60947-2 standards, confirming its safety and compliance with applicable regulations. It uses lug terminals allowing connection of wires with a cross-section of up to 25mm². The width of the breaker is 17.8mm per pole, which allows for efficient use of space in the switchgear cabinet.

Key benefits
