Overcurrent circuit breaker, 6kA BKJ63Nd series 1P 6A B characteristic BKJ63Nd 1P B6 BKJ63ND 1P B6

BKJ63Nd Series Circuit Breakers – Reliable Installation Protection

This single-pole BKJ63Nd circuit breaker with a rated current of 6A and B characteristic is a key element of any electrical installation. It provides effective protection against the effects of overloads and short circuits, protecting both devices and cables. This is particularly important in circuits with devices that draw high power during start-up, such as motors or transformers.

BKJ63Nd circuit breakers are characterized by high reliability and durability, confirmed by compliance with IEC 60898-1 and IEC 60947-2 standards. Mounting on a 35mm DIN rail simplifies and speeds up installation, and the compact dimensions (17.8mm per pole) allow for optimal use of space in the distribution board. An optical trip indicator allows for quick identification of the breaker status – whether it has tripped and requires resetting.

Application and benefits for professionals:

• Circuit Protection: Effectively protects circuits against overload and short circuit, minimizing the risk of damage and fires.
• Installation: Quick mounting on a 35mm DIN rail saves time during installation.
• Diagnostics: Optical indicator facilitates identification of the breaker status, speeding up fault location.
• Versatility: Suitable for use in domestic, commercial and industrial installations.
• Compliance with standards: Ensures safety and compliance with applicable regulations.

B characteristic – ideal for mixed circuits.

The B characteristic means that the circuit breaker reacts quickly to an increase in short-circuit current, but is more tolerant of short-term current surges, such as those occurring when starting motors or transformers. This minimizes the risk of unnecessary tripping of the circuit during normal operation of the devices. The short-circuit breaking capacity is 6kA at 240/415V AC, ensuring effective protection even in the event of serious disturbances in the network. The cross-section of the connection wires is up to 25mm², allowing connection of a wide range of wires of different thicknesses. The circuit breaker operates at temperatures from -5°C to +40°C, ensuring its reliability in various environmental conditions.
