The Siemens SIRIUS 3RA2210-1HA16-2AK6 is a non-fused reversing starter, Size S00, designed for controlling the direction of three-phase motors up to 690 V AC-3 duty. It ships as a factory-assembled unit that includes a 3RT2016-1AK62 contactor and a 3RA1921-1DA00 link module, so the reversing interlock is pre-wired and tested — no field wiring of mechanical interlocks needed.
Mounts via screw or snap-on onto 35 mm standard DIN rail in a vertical position only, with clearances: 20 mm upwards, 10 mm downwards, 9 mm to the side, and 0 mm forwards or backwards. Dimensions are 170 mm height, 90 mm width, and 97.1 mm depth — the S00 footprint keeps panel fill factor tight for a reversing starter with built-in interlock. Main contact wiring accepts stranded conductors 0.5 to 4 mm² or two conductors 0.75 to 2.5 mm² per terminal; the spring-cage or screw terminals match standard panel-building practice.
