Overcurrent circuit breaker, 6kA series BKN 2P 20A B characteristic BKN 2P B20A

Safety and reliability in your electrical installation

This two-pole overcurrent circuit breaker of the BKN series, with a rated current of 20A and B characteristic, is a key element in protecting electrical circuits. It provides effective protection against overloads and short circuits, protecting both devices and the installation. Its compact size and DIN rail mounting simplify installation and integration with the existing system.

Characteristics and application

The BKN circuit breaker with B characteristic is designed to protect circuits with moderate inrush current. This means that it works well in applications with devices that temporarily draw more current during startup – such as electric motors or transformers. The B characteristic allows it to react more slowly to short current surges, so it tolerates starting devices with a motor well. Designed to operate in 230/400V AC circuits, it offers reliable operation over a wide temperature range – from -5°C to 40°C.

Key features and benefits

• High breaking capacity: 6kA – ensures effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage.
• Two-pole design: allows protection of two phase conductors simultaneously, providing comprehensive protection.
• DIN rail mounting: quick and easy mounting in the distribution board, saving installers time.
• Wide range of wire cross-sections: accepts wires with a cross-section from 1mm² to 25mm², giving flexibility when choosing wires.
• Contact position indicator: visual information about the status of the circuit breaker (on/off) facilitates diagnostics and maintenance.
• Protection degree IP20: provides protection against touching with fingers and against the ingress of solid objects larger than 12.5 mm – standard protection for devices mounted inside distribution boards.
• Compliance with standards: LS Electric circuit breakers meet strict safety standards, guaranteeing reliable operation and compliance with regulations.
