SIRIUS 3RA2 direct starter — size S00, 90 W at 400 V
The Siemens 3RA2115-0EA15-1AK6 is a SIRIUS non-fused direct motor starter, size S00, combining a 3RT2015-1AK61 contactor, a 3RV2011-0EA15 circuit-breaker, and a 3RA1921-1DA00 link module into a single pre-assembled unit. Rated motor power is 90 W at 400 V, 120 W at 500 V, and 180 W at 690 V, with operating frequency of 50 to 60 Hz and coil voltage ranges of 93.5 to 121 V at 50 Hz and 96 to 132 V at 60 Hz. The overload release is thermal bimetallic with Class 10 trip characteristic; the short-circuit trip is magnetic, giving coordinated motor protection in a single footprint.
Panel integration — 45 mm width, snap-on DIN rail or screw mount
Mounting position is vertical; clearance requirements are 20 mm upwards, 10 mm downwards, 9 mm at the side, and 0 mm forwards or backwards — useful when laying out a dense panel. AWG equivalents are 2x (20 to 16) for the contactor and 2x (18 to 14) or 2x 12 for larger runs.
Active production — sourcing posture for BOM planning
Operating temperature range is -20 to +60 °C; storage range -50 to +80 °C; transport range -55 to +80 °C — suitable for panel environments with moderate thermal cycling. Rated insulation voltage is 690 V with surge voltage resistance of 6 kV, and degree of pollution 3 — appropriate for industrial control panels with conductive contamination risk.
