Overcurrent circuit breaker, 6kA series BKN 4P 20A B characteristic BKN 4P B20A

4-pole overcurrent circuit breaker 20A B characteristic

This four-pole circuit breaker from the BKN series, with a rated current of 20A and B characteristic, is a reliable protection for electrical installations. Designed to protect circuits against overload and short circuit, it ensures safe use and long-term system stability. Manufactured by LS ELECTRIC, a manufacturer renowned for quality and innovation in the electrical installation industry.

Protection and application

The BKN circuit breaker with B characteristic reacts quickly to current increase, but is more tolerant to short-term surges than circuit breakers with C characteristic. This makes it ideal for protecting lighting circuits, socket circuits and other loads with low inrush current. Its short-circuit breaking capacity is 6kA, which guarantees effective protection even in the event of serious disturbances in the network. DIN rail mounting simplifies and speeds up installation.

Construction features and parameters

This circuit breaker has been designed with durability and reliability in mind. The housing made of high-quality materials provides resistance to mechanical damage and external factors. The cross-section of the conductors connected to the circuit breaker is from 1 to 25 mm², which provides great flexibility in choosing conductors adapted to the needs of the installation. The degree of protection IP20 indicates protection against touching with a finger and against the ingress of solid objects larger than 12.5 mm. The circuit breaker operates in a temperature range from -5°C to 40°C, which allows it to be used in various environmental conditions. Additionally, it has a visual indication of the contact position, which facilitates the diagnosis of the circuit breaker status. The rated voltage is 230/400V AC.
