The horsepower table spans 1 hp at 110/120 V up to 14 A at 480 V and 11 A at 600 V — useful for matching NEMA motor frames. ## Busbar snap-on and panel fit Snaps directly onto 60 mm busbar systems — no DIN rail adapter needed. The 45 mm width and 155 mm depth fit standard S00 feeder slots; vertical mounting position is required for proper thermal convection through the overload block. Clearance requirements: 50 mm upwards, 20 mm forwards, 20 mm at the side, and 10 mm downwards — plan the gland plate and wireway accordingly. Backwards clearance is 0 mm, so the unit can sit flush against the backplane. Main circuit terminals are spring-loaded — no screw-torque check needed, but the stripped length must match the cage entry. The supplied contactor is 3RT2018-2BB41 and the link module is 3RA2911-2AA00; the BOM is self-contained for a direct-on-line start. ## Lifecycle and sourcing — current production, quoted to order The 24 V coil is standard for control panels with 24 VDC power supplies. Operating temperature range is -20 to +60 °C; storage and transport range is -50 to +80 °C.","metaTitle":"Siemens 3RA2110-4AS18-1BB4 SIRIUS Motor Starter, 16 A AC-3","metaDescription":"Siemens SIRIUS direct-on-line starter, size S00, 16 A at 400 V AC-3, CLASS 10 trip, snaps onto 60 mm busbars.
