The Siemens SIRIUS 3RA2210-0KA15-2AK6 is a non-fused reversing load feeder in Size S00 — a factory-assembled combination of a reversing contactor, a thermal bimetallic overload relay, and a link module, all mounted on a common base. It ships with the 3RT2015-1AK62 contactor and the 3RA1921-1DA00 link module, so the reversing pair and overload are coordinated out of the box. Rated for AC-3 duty up to 690 V, it delivers 370 W at 400 V and 750 W at 690 V, with a 0.5 hp rating at both 460/480 V and 575/600 V — sized for small reversing motor loads like conveyors, dampers, or valve actuators that need forward/reverse control in a compact footprint.
Dimensions are 170 mm high, 90 mm wide, and 97.1 mm deep — the S00 frame keeps panel density tight. Main contact wiring accepts stranded conductors from 0.5 to 4 mm², or two conductors of 0.75 to 2.5 mm² each — sufficient for the motor currents this size handles.
