It ships with the 3RT2015-1FB41 contactor, 3RV2011-0FA10 circuit-breaker, 3RA1921-1DA00 link module, and 8US1251-5DS10 busbar adapter — all screw-type terminated for the main and control circuits. ## Ratings and operating envelope Rated 120 W at 400 V and 0.5 A at 480 V, with a maximum AC-3 switching voltage of 690 V, operating at 50 to 60 Hz. The control coil is rated 24 V DC — confirm your control transformer or PLC output matches this voltage before wiring. Ambient operating range is -20 to +60 °C; storage and transport tolerance extends from -50 to +80 °C. Mounting position is vertical only. Overload protection uses a thermal bimetallic element; short-circuit detection is magnetic. An auxiliary switch can be added via the product extension slot. ## Mounting and panel fit The unit measures 155 mm deep, 45 mm wide, and 200 mm tall — a compact footprint for size S00. It snaps directly onto 60 mm busbar systems, not onto DIN rail. Clearance requirements: 50 mm above, 20 mm in front, 20 mm at the sides, 10 mm below, and 0 mm behind the unit.","metaTitle":"Siemens 3RA2110-0FD15-1FB4 SIRIUS Direct Starter, S00","metaDescription":"Siemens 3RA2110-0FD15-1FB4 SIRIUS direct online starter, size S00, CLASS 10 trip, 24 V coil, snaps onto 60 mm busbars.
