Overcurrent circuit breaker, 6kA BKJ63Nd series 2P 32A characteristic D BKJ63Nd 2P D32 BKJ63ND 2P D32

Overcurrent circuit breaker BKJ63Nd 2P 32A is a reliable protection for electrical installations, designed for both home and commercial use. The device effectively protects circuits against overloads and short circuits, ensuring safe operation and minimizing the risk of failure. Made of high-quality materials, it guarantees long-lasting and trouble-free operation.

Characteristics and application

The BKJ63Nd circuit breaker is characterized by a D characteristic, which means a delayed response to short-term current increases. This makes it particularly recommended for protecting circuits with receivers with high inrush current, such as electric motors, transformers or impulse power supplies. Mounting is done on a standard 35mm DIN rail, which facilitates installation and integration with existing electrical infrastructure. Designed for operation in installations with a voltage of 230/400V AC.

Construction and product features

The construction of the circuit breaker is based on solid insulating and conductive materials, which ensures high resistance to environmental conditions and long-term stability of parameters. It has a two-pole (2P) design, which allows disconnecting both the phase and neutral wire in the event of a failure. The use of screw and lug terminals allows for flexible connection of wires with a cross-section of up to 25mm². Additionally, the circuit breaker has a visual indicator of contact position, which facilitates quick identification of the device status.

Parameters and compliance with standards

The BKJ63Nd circuit breaker meets the requirements of IEC 60898-1 and IEC 60947-2 standards, which confirms its safety and reliability. It has a short-circuit breaking capacity of up to 6kA at 415VAC. Suitable for operation in ambient temperature from -5°C to +40°C. The width of the circuit breaker is 17.8mm per pole, which allows for efficient use of space in the switchgear cabinet. The device has a protection degree of IP20, protecting against touching with fingers and against the ingress of solid objects larger than 12.5mm.
