It is rated for AC-3 motor duty at up to 690 V, 1.1 kW at 400 V, 50/60 Hz, with a thermal (bimetallic) overload release and magnetic short-circuit trip, trip Class 10. ## Mounting and clearances — 35 mm DIN rail or screw Fastens by screw or snaps onto a 35 mm standard mounting rail, vertical mounting position only. Overall dimensions: 198 mm height, 45 mm width, 97 mm depth. Clearance requirements: 50 mm upwards, 20 mm forwards, 10 mm downwards, 20 mm at the side, 0 mm backwards — plan the enclosure layout accordingly. ## Terminals and environmental limits Spring-loaded terminals on both the main current circuit and the auxiliary/control circuit — no screw torque to verify, which simplifies panel build and reduces loose-connection callbacks. Operating temperature range -20 to +60 °C, storage and transport -50 to +80 °C, relative humidity 10 to 95 % during operation. Surge voltage resistance rated at 6 kV.","metaTitle":"Siemens 3RA2115-1DE15-1FB4 SIRIUS Direct Starter, S00","metaDescription":"Siemens 3RA2115-1DE15-1FB4 SIRIUS direct online starter, size S00, 1.1 kW at 400 V AC-3, Class 10.
