BK/RK Series – Circuit Breakers

A circuit breaker is an electrically operated device designed to protect an electrical circuit from damage caused by excessive currents due to overloads or short circuits.

Miniature circuit breakers are installed directly above the load and are designed to protect final circuits. They are ideal for circuit protection in industrial, commercial, and residential sectors, providing the following functions:

• Protection against short circuits and overload currents
• Isolation
• Protection against indirect contact
