Overcurrent circuit breaker, 6kA BKN series 1P 2A B characteristic BKN 1P B2A

Overcurrent switch for protection of electrical installations

This single-pole overcurrent switch from the BKN series, with a rated current of 2A and B characteristic, is a reliable safety element in every electrical installation. Designed to protect against overloads and short circuits, it ensures safe use and long-term stability. It is a key component for installers building new systems or modernizing existing ones.

Characteristics and application

The BKN 1P B2A switch is designed for mounting on a 35mm DIN rail. Its compact dimensions (1 module wide) allow for efficient use of space in the distribution board. The B characteristic means that the switch reacts quickly to an increase in current, which is particularly important in circuits with devices with high inrush current – such as motors or transformers. It provides effective protection of wires and electrical devices against damage caused by overload or short circuit. Short-circuit strength up to 6kA guarantees safety even in the event of serious failures.

Construction and installation

The switch is made of high-quality materials, which translates into its durability and reliability. It has lug terminals allowing the connection of wires with a cross-section of up to 2.5mm². Installation is done by snapping onto a standard DIN rail, which greatly simplifies and speeds up installation. The IP20 degree of protection provides protection against accidental contact, but does not protect against the effects of water – remember to provide appropriate working conditions. This switch complies with IEC60947-2 standards, confirming its safety and quality.
