Siemens Marine 3RV2 S0 10A 440V Marine — Motor Control. As a Motor Protection Switch, it is normally installed in a motor-control centre, switchboard, local starter panel or dedicated drive cabinet. In that role, its primary purpose is to start, protect or regulate an electric motor according to the connected machinery duty. Direct-on-line starters, soft starters, protection switches and VFDs differ in switching and speed-control capability, but all depend on sound power connections, protection settings and control circuits. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
