Overcurrent circuit breaker, 6kA BKN series 2P 16A characteristic D BKN 2P D16A

Overcurrent circuit breaker – reliable protection for your installation

This two-pole overcurrent circuit breaker of the BKN series, with a rated current of 16A and D characteristic, is a key element ensuring safety in every electrical installation. Designed to protect circuits against overloads and short circuits, it performs well in both residential and commercial buildings. Its compact size and DIN rail mounting simplify installation and integration with existing systems.

Characteristics and application

The BKN circuit breaker with D characteristic is distinguished by a delayed reaction to current increase. This means that it allows for short-term exceeding of the rated current without disconnecting the circuit – which is particularly important for devices with electric motors or other loads with high inrush current. This avoids unnecessary shutdowns caused by momentary voltage spikes. The rated short-circuit breaking capacity of 6kA guarantees effective protection in the event of serious disturbances in the network.

These circuit breakers are used to protect:

• Lighting
• Socket outlets
• Heating circuits
• Electrical devices with motors (e.g. pumps, fans)
• Electrical installations in residential and commercial buildings

Construction and user parameters

The BKN circuit breaker is characterized by a solid construction and high quality workmanship. Adapted for mounting on a DIN rail, which greatly facilitates its installation and replacement. It has a visual indication of contact status, allowing for quick identification of any problems with the circuit. The cross-section of the conductors connected to the circuit breaker is from 1 to 25 mm², which provides flexibility in choosing cables of the appropriate thickness. Operation at temperatures from -5°C to 40°C guarantees reliable operation even in difficult environmental conditions. The degree of protection IP20 provides protection against touching with fingers and against the ingress of solid objects larger than 12.5 mm.
