The ETIMAT10 3P B 25A 10kA AC automatic circuit breaker is a basic protection automation device, designed to limit the effects of short circuits and overloads in electrical installations. When the current flow exceeds the rated current, the breaker interrupts its operation, offering protection to devices and installations, as well as protection for people from electric shock and fire.
It is mainly used in residential building electrical installations to protect lighting circuits, sockets, and controls. Its design allows for the installation of additional equipment, such as auxiliary contacts, for remote signaling of the device's operation.
The device can be equipped with shunt releases that remotely open the circuit breaker's contacts, as well as undervoltage releases to activate the breaker in case of a voltage drop.
Circuit breakers are mounted on the TH-35 support rail. The short circuit breaking capacity of this breaker is 10 kA.
