Overcurrent circuit breaker, 6kA BKJ63Nd series 1P 20A characteristic C BKJ63Nd 1P C20 BKJ63ND 1P C20

Overcurrent circuit breaker BKJ63Nd is a safety element protecting electrical installations against overloads and short circuits. Designed for mounting on a DIN rail, it provides reliable protection in circuits with a voltage of 230/400V AC. Model BKJ63Nd 1P C20, with a rated current of 20A and C characteristic, is particularly recommended for protecting circuits with a load characteristic with elements with a high inrush current – such as motors or transformers.

This single-pole circuit breaker (1P) from the BKJ63Nd series is characterized by high efficiency and durability. Its construction based on solid materials guarantees long-term and trouble-free operation. The rated short-circuit breaking capacity is 6kA, which ensures effective disconnection of the circuit in the event of a dangerous short-circuit current.

• Overload and short-circuit protection: Ensures the safety of the electrical installation and connected devices.
• C characteristic: Allows for short-term exceeding of the rated current without tripping the breaker, which is important when servicing devices with motors or transformers. The C characteristic allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well.
• Short-circuit breaking capacity of 6kA: Guarantees effective disconnection of the circuit in the event of a short circuit.
• DIN rail mounting: Enables quick and easy mounting in a distribution box.
• Width 17.8mm: Compact dimensions allow for efficient use of space in the distribution box.
• Operating temperature: The breaker maintains its properties in the temperature range from -5°C to +40°C, making it a universal solution for various environmental conditions.

BKJ63Nd circuit breakers meet the requirements of IEC 60898-1 and IEC 60947-2 standards, which confirms their compliance with European safety standards. These are reliable and safe devices, ideal for both domestic and industrial applications. Designed to protect electrical installations in residential, commercial and industrial buildings – everywhere where high reliability and safety of operation are required.
