Description
Miniature Circuit Breakers is an automatic electromechanical switch and it is a device that protects against both short circuit error and overload current, and due to its automaticity, after disconnection, returns to the circuit again. The miniature switches are non-adjustable and can operate both magnetically and thermally. Miniature keys include different divisions, which are based on the cutoff speed and the number of their bridges. Based on the type of application and the type of protection required, a special circuit breaker must be choosing that provides the necessary protection for the system in addition to cutting off all unwanted currents, otherwise there will be a lot of damage to equipment, circuits and human life. is entered.
