Motor Starter Protectors
SIRIUS 3RV circuit-breakers are compact, current-limiting circuit-breakers (motor starter protectors MSP). They ensure safe shutdown in the event of a short-circuit and protect motor applications against overload. Furthermore, they are also suitable for manually switching loads under field conditions and safely isolating the load from the main power supply when maintenance work or modifications need to be undertaken.
