Overcurrent circuit breaker, 6kA series BKN 3P 6A characteristic D BKN 3P D6A

Overcurrent circuit breaker from the BKN series is a three-pole protection device designed for electrical installations with a voltage of 230/400V AC. The rated current (Inom) is 6A, and the D characteristic provides delayed tripping during overloads, which is particularly important for devices with motors or other loads with high inrush current.

This model, designated as BKN 3P D6A, is characterized by high effectiveness in protecting circuits against the effects of overloads and short circuits – the short-circuit breaking capacity is as high as 6kA. Mounting is done on a standard DIN rail, which simplifies and speeds up installation. This circuit breaker is compatible with wires with a cross-section from 1 to 25 mm², which provides flexibility in choosing the appropriate wire for the application.

• D characteristic: Delayed tripping allows for trouble-free starting of devices with motors, pumps or other loads generating high inrush current. This avoids unnecessary tripping of the circuit breaker during normal operation.
• Short-circuit breaking capacity of 6kA: Provides effective protection of the installation in the event of a short circuit, minimizing the risk of damage and fire.
• DIN rail mounting: Standard mounting simplifies integration with existing switchboards and control cabinets.
• Wide range of wire cross-sections (1-25mm²): Allows adaptation to different types of installations and loads.
• Protection degree IP20: Protection against touching with fingers and against the ingress of solid objects larger than 12.5 mm – standard protection for devices mounted inside electrical cabinets.

The BKN 3P D6A circuit breaker is a product of LS ELECTRIC, a well-known manufacturer of electrical components. Designed for use in temperatures from -5°C to 40°C, which makes it a universal solution for most indoor applications. It has contact status visualization, which facilitates diagnostics and identification of problems in the installation. It is a reliable and effective solution for professionals and end-users looking for solid electrical protection.
