Overcurrent circuit breakers BKJ63Nd series – reliable installation protection

This two-pole overcurrent circuit breaker BKJ63Nd with a rated current of 1A and characteristic C is a key element in protecting electrical installations. Replacing the BKN series, it offers improved technical parameters and provides effective protection against overloads and short circuits in residential, commercial and industrial buildings. The design with a separate terminal for the conductor and the busbar facilitates installation and ensures a secure connection.

Functions and application

Circuit breakers from the BKJ63Nd series are designed to protect electrical circuits against the effects of overloads and short circuits. Characteristic C means that the circuit breaker reacts to currents 5 to 10 times higher than the rated current, making it suitable for protecting circuits with devices generating short-term current surges, such as motors. This minimizes the risk of unnecessary tripping of the device during normal operation.

Design and characteristic features

The BKJ63Nd 2P C1A circuit breaker has been designed for easy mounting on a standard 35mm DIN rail. This ensures quick and trouble-free installation in electrical distribution boards. Made of high-quality materials, it guarantees long-lasting and reliable operation. It meets the requirements of IEC 60898-1 and IEC 60947-2 standards, confirming its safety and compliance with applicable standards. Suitable for operation in ambient temperatures from -5°C to +40°C.

• Wide range of applications: ideal for protecting lighting circuits, socket circuits and electrical appliances in residential, commercial and industrial buildings.
• Characteristic C: provides optimal protection against overloads and short circuits while avoiding unnecessary tripping caused by short-term current surges.
• Two-pole design (2P): allows disconnection of both phase and neutral, ensuring complete circuit isolation.
• DIN rail mounting: facilitates quick and safe installation in electrical distribution boards.
• Compliance with standards: meets the requirements of IEC 60898-1 and IEC 60947-2, guaranteeing safety of use.
• Improved terminal design: separate terminal for the conductor and busbar ensures a secure electrical connection.
• Adapted to work in various conditions: the operating temperature range from -5°C to +40°C allows use in a wide range of environments.
