Overcurrent circuit breaker, 6kA BKJ63Nd series 3P 2A characteristic C BKJ63Nd 3P C2 BKJ63ND 3P C2

Protection of electrical installations and devices

Overcurrent circuit breaker BKJ63Nd 3P with a rated current of 2A and C characteristic is a reliable protection element in every electrical installation. Designed to protect against the effects of overloads and short circuits, it ensures safe use and long life of connected devices. It is the successor to the popular BKN series, offering improved technical parameters and a more convenient solution in the form of a separate terminal for the wire and busbar.

Functionality and application

Circuit breakers from the BKJ63Nd series are widely used in both residential and industrial construction. They are suitable for protecting electrical circuits in residential buildings, commercial facilities and industrial installations. Thanks to their compact size (17.8mm wide per pole) they are easy to mount on a standard 35mm DIN rail. Adapted to work with a voltage of 240/415V AC, they provide versatility and compatibility with various power systems.

Characteristics and parameters

The C characteristic of the circuit breaker means that it is designed to protect circuits with devices generating inrush currents during start-up - e.g. electric motors or transformers. This allows to avoid unnecessary tripping of the circuit breaker during normal operation of these devices, while ensuring effective protection against overloads and short circuits. This circuit breaker has a short-circuit breaking capacity of up to 6kA, which guarantees safety even in the event of serious disturbances in the electrical network. Compliance with IEC 60898-1 and IEC 60947-2 standards confirms its high quality and reliability. The possibility of connecting wires with a cross-section of up to 25mm² provides flexibility when choosing the appropriate wire matched to the load. The circuit breaker is designed for mounting on a 35mm DIN rail, which facilitates its installation and replacement.
