Overcurrent circuit breaker, 6kA series BKN 3P 20A B characteristic BKN 3P B20A

Overcurrent circuit breaker BKN 3P B20A is a three-pole installation circuit breaker designed to protect electrical circuits against overloads and short circuits. It is characterized by a rated current of 20A and a B characteristic, which means it is ideal for protecting circuits with moderate inrush current - such as lighting, sockets in residential premises, or circuits with resistive loads.

Protection and application

BKN series circuit breakers, including the BKN 3P B20A model, provide effective protection of the electrical installation. The B characteristic means that the circuit breaker reacts quickly to short-circuit currents, while tolerating short-term current surges during device start-up. This is important for receivers with electric motors or other elements generating high starting current. The three-pole design (3P) means that the circuit breaker protects all three phases in a three-phase installation.

Construction and characteristics

BKN circuit breakers are characterized by a compact design and easy mounting on a TH35 rail. Solid construction guarantees reliable operation and long service life. They are adapted to work in standard environmental conditions, ensuring safe operation for a long time. The rated breaking capacity of 6kA means that the circuit breaker is able to interrupt a short-circuit current with a value of 6000 amperes - this is an important parameter for ensuring the safety of the installation. Made of high-quality materials resistant to mechanical damage and external factors.

Installation and compatibility

The circuit breaker is mounted by snapping onto a standard TH35 rail - no additional tools or specialized knowledge are required. Compatible with other protective devices from the BKN series, allowing for the construction of comprehensive electrical installation protection systems. Installers will appreciate the simplicity of installation and reliable operation of this circuit breaker, and end users - the safety and peace of mind resulting from solid protection of their electrical installation.
