It's rated 45 A at AC-3 400 V, which means it handles full-voltage starting of three-phase motors up to that current without the need for separate component selection and wiring. The Class 10 trip class gives you a standard thermal protection curve for motors that reach full speed within 10 seconds — covers most pump, fan, and compressor loads you'd see in a panel. The bimetal overload release tracks motor heating directly, so you don't need a separate overload relay downstream. ## Mounting and panel fit — S2 frame on dual DIN rails This starter mounts with screws or snaps onto two parallel 35 mm DIN rails — the S2 frame is wide enough at 55 mm that the dual-rail footprint keeps it stable under vibration and contactor chatter. Panel clearance: 150 mm depth, 274 mm height, with 50 mm upwards and 32 mm forwards clearance for wiring and arc venting. Mounting position is vertical or horizontal, so you can lay it into a shallow enclosure if needed. ## Duty ratings and motor power coverage At AC-3 duty (squirrel-cage motor starting), the 3RA2130-4VA36-0AP0 carries 45 A at 400 V and 45 A at 480 V — the same current rating across both voltages, so motor power at 400 V works out to 22 kW. At 600 V it's still 45 A, giving you consistent switching capacity across common North American and European line voltages. The insulation voltage rating is 690 V, so this starter can sit in a 480 V or 600 V panel without derating the dielectric gap. Operating temperature range is -20 to +60 °C, storage and transport -50 to +80 °C — fine for most unconditioned plant-floor environments.","metaTitle":"Siemens 3RA2130-4VA36-0AP0 SIRIUS Motor Starter, 45 A AC-3","metaDescription":"Siemens 3RA2130-4VA36-0AP0 SIRIUS direct online motor starter, 45 A at AC-3 400 V, S2 frame, Class 10 thermal overload.
