S00 non-fused load feeder, direct starter
The 3RA2110-1BD15-1AK6: This is a Siemens SIRIUS 3RA2 non-fused load feeder in the S00 frame size, configured as a direct starter — meaning it combines a contactor and a thermal overload relay in one package, no separate fusing required upstream for short-circuit protection within its rating. It ships with a 3RT2015-1AK61 contactor and a 3RA1921-1DA00 link module, plus a 8US1251-5DS10 busbar adapter for snapping onto 60 mm busbar systems — the panel builder gets a pre-coordinated set, not a pile of loose parts.
Rated voltage and power coverage
Maximum operating voltage is 690 V in AC-3 duty — the highest common industrial motor voltage in 50 Hz markets, so this feeder covers 400 V, 480 V, 575 V, and 690 V systems without derating the switching capacity. At 400 V 50 Hz it is rated for 750 W motor output; at 690 V the same feeder handles 1 100 W — the higher voltage reduces current for the same power, keeping the contactor within its AC-3 switching capability. For 60 Hz markets: at 460/480 V it delivers 0.75 hp, at 575/600 V it delivers 1 hp — the horsepower ratings track the voltage step, not the frequency change.
Mounting and clearance requirements
The feeder snaps onto 60 mm busbar systems — no DIN rail needed if the panel uses busbar distribution; the supplied adapter locks it in place. Mounting position is vertical only — horizontal mounting changes the thermal overload calibration because the bimetallic strip relies on convection for its trip curve. Clearance distances: 20 mm upwards, 10 mm downwards, 9 mm to the side, zero forwards and backwards — the panel layout needs those gaps for heat dissipation and arc flash containment, not just wire bending space. Dimensions are 45 mm wide by 200 mm tall by 155.1 mm deep — the width is the critical panel fill factor; at 45 mm it occupies one standard 45 mm slot on a busbar or DIN-rail grid.
Environmental and compliance notes
Operating temperature range is -20 to +60 °C; storage and transport range is -50 to +80 °C — the wider storage window means it can sit in an unheated warehouse without damage. Degree of pollution 3 — rated for conductive pollution in industrial atmospheres (dust, oil mist, condensation), so it does not need an additional enclosure in a typical panel environment. Substance prohibitance date is 10/01/2009 — this marks the RoHS compliance baseline; the feeder meets the EU RoHS substance restrictions as of that date.
