What this SIRIUS load feeder packs
The Siemens 3RA2110-0EA15-1AK6 is a SIRIUS non-fused load feeder, size S00, wired as a direct starter. It ships as a pre-assembled unit combining a contactor (3RT2015-1AK61), a thermal bimetallic overload relay, and a circuit-breaker (3RV2011-0EA10) with a magnetic short-circuit trip — all on a 45 mm wide footprint that snaps onto a 35 mm DIN rail.
The 45 mm width and 167.2 mm height fit a standard S00 feeder slot in a SIRIUS panel layout. Clearance: 20 mm upward, 10 mm downward, 9 mm at the side — no space needed forward or backward. That's another SKU that slots into a crowded enclosure without re-spacing the gland plate.
