Overcurrent circuit breaker, 6kA BKN series 1P 40A characteristic C BKN 1P C40A

Overcurrent circuit breaker of the BKN series is a reliable element protecting electrical installations against overloads and short circuits. Model BKN 1P C40A, designed for mounting on a DIN rail, provides effective protection for circuits with a rated current of 40A. It is characterized by a high breaking capacity – up to 6kA, which guarantees safety in the event of a failure.

This single-pole circuit breaker (1P) with characteristic C is ideal for protecting circuits with a mixed character, where both resistive (e.g., light bulbs) and inductive loads (e.g., motors) occur. Characteristic C allows for short-term exceeding of the rated current without unnecessary tripping, which is especially important when starting devices with electric motors – this avoids irritating false alarms. Applications in home installations, commercial buildings and industrial facilities are just some of the possibilities.

Design and application

BKN circuit breakers have been designed with easy installation and intuitive operation in mind. The solid construction and high-quality materials ensure long-lasting and trouble-free operation. A wide range of rated voltage (230/400V AC) makes it a universal solution for various electrical installations. This circuit breaker is used to protect:

• lighting,
• socket outlets,
• distribution circuits,
• electrical devices of an inductive and resistive nature.

Advantages and benefits

• High breaking capacity (6kA): ensures effective protection against the effects of short circuits.
• Characteristic C: ideal for circuits with inductive and mixed loads – minimizes the risk of unnecessary tripping.
• DIN rail mounting: facilitates and speeds up installation.
• Versatility: can be used in various types of electrical installations (home, commercial, industrial).
• Reliability: solid construction guarantees long-lasting, trouble-free operation.
• Compliance with standards: ensures safety of use and compliance with applicable regulations.
