Automatic switch ETIMAT10 3P B 16A 10kA AC - 002125716. The circuit breaker is one of the essential and commonly used protection automation devices used to limit the effects arising from short circuits and overloads of the electrical installation. The flow of current that is much higher than the nominal current of the circuit breaker causes its operation to stop and the interruption of the electrical circuit. This type of action aims to protect devices and installations from damage, protect people from electric shock, and ultimately from fire.

Due to its parameters, it is most commonly used in electrical installations of residential buildings to protect lighting circuits, outlets, and controls. The design of the switches allows for the installation of additional equipment, e.g., auxiliary contacts, thanks to which remote signaling of the device's operation is possible.

The device can also be equipped with shunt releases, which remotely open the contacts of the circuit breaker when voltage appears, or with under-voltage releases, which activate the circuit breaker in case of voltage drop compared to the nominal value.
