Overcurrent circuit breaker, 6kA BKJ63Nd series 2P 10A characteristic D BKJ63Nd 2P D10 BKJ63ND 2P D10

Overcurrent switch – reliable installation protection

This two-pole overcurrent switch from the BKJ63Nd series is a key element of every safe electrical installation. Designed to protect circuits against the effects of overloads and short circuits, it ensures stable and long-lasting operation. It is characterized by high efficiency and is intended for both domestic and professional applications.

Characteristics and application

The switch with characteristic D is particularly recommended for protecting circuits powering devices with high inrush current, such as motors, transformers or impulse power supplies. Characteristic D allows for temporary overloads without unnecessary tripping of the circuit, which is important for devices requiring higher current during start-up. This ensures continuity of power supply and minimizes the risk of downtime.

The BKJ63Nd 2P 10A switch is perfect for installations:

• Lighting
• Socket outlets
• Powering electrical devices with high power consumption
• In residential, commercial and industrial buildings

Construction and mounting

The switch is mounted on a standard 35mm DIN rail, which facilitates its installation and replacement. It has screw terminals allowing connection of wires with a cross-section of up to 25mm². The width of the switch is 17.8mm per pole, which allows for efficient use of space in the switchgear cabinet. The construction of the switch ensures high reliability and durability, confirmed by a certificate of conformity with IEC 60898-1 and IEC 60947-2 standards. The electrical endurance of the device is as much as 10,000 operating cycles.
