Overcurrent circuit breaker, 6kA BKJ63Nd series 2P 10A characteristic C BKJ63Nd 2P C10 BKJ63ND 2P C10

Overcurrent circuit breaker BKJ63Nd 2P 10A is a reliable safety element for electrical installations, both in residential and industrial construction. Designed to protect against the effects of overloads and short circuits, it ensures safe and long-lasting operation of circuits. The two-pole (2P) design allows disconnection of the phase and neutral, which increases safety.

Characteristics and application

The circuit breaker is characterized by a C characteristic, which means that its operation is delayed in relation to sudden current surges. This makes it ideal for circuits with receivers generating high starting currents, such as electric motors or transformers. This ensures stable operation of the installation without unnecessary shutdowns caused by temporary overloads. The rated current of 10A makes this circuit breaker suitable for protecting circuits with medium power consumption.

Construction and mounting

The BKJ63Nd circuit breaker is mounted on a standard 35mm DIN rail, which facilitates its installation and replacement. Compact dimensions (17.8mm per pole) allow for efficient use of space in the switchgear cabinet. The ability to connect wires with a cross-section of up to 25mm² provides flexibility when selecting appropriate cables. Made of high-quality materials, it guarantees durability and resistance to mechanical damage and environmental conditions.

The width of the circuit breaker is 17.8mm per pole, which facilitates mounting in tight switchgear cabinets. The ability to connect wires with a cross-section of up to 25mm² provides flexibility when selecting appropriate cables. The electrical life of the device is 10,000 cycles, and the mechanical life – 20,000 cycles, which confirms its durability and reliability. The degree of protection IP20 provides protection against finger contact and against the ingress of solid objects larger than 12.5 mm. The rated voltage is 415VAC for 2-4 pole circuits and 240VAC for 1-pole circuits + N.

LS Electric BKJ63Nd series circuit breakers meet the requirements of IEC 60898-1 and IEC 60947-2 standards, which confirms their safety and compliance with applicable regulations. The short-circuit breaking capacity is 6kA at 240/415VAC, which ensures effective protection of the installation in the event of a failure.
