What this SIRIUS 3RA2 load feeder is
The Siemens 3RA2110-0JA15-1AK6 is a SIRIUS-branded non-fused load feeder, assembled as a direct starter in Size S00. It ships as a pre-integrated unit containing a 3RT2015-1AK61 contactor, a 3RV2011-0JA10 circuit-breaker with magnetic short-circuit trip and thermal bimetallic overload release, and a 3RA1921-1DA00 link module. Rated for AC-3 motor switching up to 690 V at 50/60 Hz, with a Class 10 trip characteristic. The thermal overload release (bimetallic) and magnetic short-circuit trip are built into the supplied circuit-breaker, so the feeder handles both overload protection and short-circuit interruption in one DIN-rail package.
Mounts vertically on 35 mm DIN rail — screw and snap-on. Clearance: 20 mm upwards, 10 mm downwards, 9 mm at the side, 0 mm forwards or backwards. That 45 mm width is the standard Size S00 footprint, so it slots into a panel layout alongside other S00 devices without extra spacing. Pollution degree 3 environment — suitable for control panels in industrial atmospheres where conductive pollution may occur.
