Overcurrent switch, 6kA BKJ63Nd series 3P 1A characteristic B BKJ63Nd 3P B1 BKJ63ND 3P B1

Overcurrent circuit breaker BKJ63Nd – reliable installation protection

This three-pole overcurrent circuit breaker BKJ63Nd with a rated current of 1A and B characteristic is a key element of every safe electrical installation. It provides effective protection against overloads and short circuits, protecting both devices and cables. It is a successor to the discontinued BKN 3P B1A model, which means maintaining compatibility in existing systems.

Characteristics and application

Circuit breakers with B characteristics are particularly recommended for protecting circuits with devices with high inrush current, such as motors or transformers. The B characteristic allows for short-term exceeding of the rated current without unnecessary tripping, which is important when starting these devices. This circuit breaker is used in building, industrial installations and in electrical switchboards. The possibility of mounting on a 35mm DIN rail makes installation easier and faster.

Key features and benefits

• High breaking capacity: 6kA at 240/415VAC – guarantees effective disconnection of the circuit in the event of a short circuit.
• B characteristic: Ideal for protecting circuits with devices with high inrush current, minimizing the risk of false tripping.
• Three-pole design (3P): Provides comprehensive protection for three-phase electrical circuits.
• Rated current 1A: Suitable for protecting circuits with lower power consumption.
• DIN rail mounting: Enables quick and easy mounting in the switchboard.
• Compliance with standards: Meets the requirements of IEC 60898-1 and IEC 60947-2 standards, which confirms its safety and reliability.
• Possibility of connecting cables up to 25mm²: Provides flexibility when choosing the cable cross-section.
• Compact dimensions: Width of 17.8 mm per pole allows for efficient use of space in the switchboard.

The circuit breaker is characterized by a rated current of 1A, has three poles (3P) and a B characteristic. The breaking capacity is 6kA at 240/415VAC. It has Lug-type terminals allowing the connection of cables with a cross-section of up to 25mm². It is mounted on a 35mm DIN rail.

This circuit breaker is a solid solution for professionals and end-users looking for reliable electrical installation protection. Its compact size and easy installation make it an ideal choice for both new and modernized installations.
