Overcurrent circuit breaker, 6kA BKJ63Nd series 1P 2A characteristic C BKJ63Nd 1P C2 BKJ63ND 1P C2

Overcurrent circuit breakers of the BKJ63Nd series – reliable protection for your installation

The BKJ63Nd overcurrent circuit breaker is a safety element for electrical installations, designed to protect against the effects of overloads and short circuits. This device, characterized by high reliability and durability, finds application in both domestic and industrial installations. The BKJ63Nd 1P model with a rated current of 2A and characteristic C provides effective protection for circuits with specific requirements.

Construction and application

The BKJ63Nd circuit breaker belongs to the family of LS Electric installation circuit breakers, known for their high quality and compliance with applicable safety standards. The construction based on the bimetallic and electromagnetic principle guarantees a quick and precise reaction in the event of a dangerous condition in the installation. Characteristic C means that the circuit breaker reacts with a delay to short-term current increases, which is particularly important for loads with motors or transformers – avoiding unnecessary tripping when devices start up. The single-pole design (1P) makes this circuit breaker ideal for protecting individual circuits.

Key features and benefits

• High breaking capacity: 6kA – ensures effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage and fire.
• Characteristic C: Optimal for circuits with pulsed or inductive loads (e.g. motors, transformers), preventing false tripping during start-up.
• DIN rail mounting: Standard mounting on a 35mm DIN rail simplifies and speeds up installation and replacement of the circuit breaker.
• Durable construction: Made of high-quality materials guarantees long life and reliable operation of the device.
• Compliance with standards: Meets the requirements of IEC 60898-1 and IEC 60947-2 standards, confirming its safety and quality.
• Wide rated voltage range: Suitable for operation in 240/415VAC installations (depending on the number of poles).
• Compact dimensions: Allows mounting in tight electrical panels.

Technical parameters in practice

The BKJ63Nd 1P C2A circuit breaker is designed to operate in an ambient temperature from -5°C to +40°C, making it a universal solution for various operating conditions. The short-circuit breaking capacity of 6kA ensures effective protection against the effects of sudden overvoltages. Thanks to the use of characteristic C, this circuit breaker is perfect for circuits supplying devices generating high starting currents, such as electric motors or transformers. Mounting on a 35mm DIN rail significantly simplifies the installation process and subsequent replacement of the device if necessary.
