S00 reversing starter, 0.25 A AC-3, Class 10
The 3RA2210-0CA15-2AP0: This is a Siemens SIRIUS reversing starter — a pre-assembled combination of a contactor pair and overload relay in one package, sized S00. The unit ships with a 3RT2015-1AP02 contactor and a 3RA1921-1DA00 link module pre-integrated — no separate wiring between the reversing contactors and the overload block.
Mounting and panel fit — 90 mm wide, DIN-rail snap-on
Mounts vertically on 35 mm DIN rail via the snap-on foot, or with screws for a fixed panel install. The envelope is 170 mm tall by 90 mm wide by 97 mm deep — the 90 mm width is the critical panel-space dimension; it occupies three standard 18 mm module positions plus a bit. Clearance requirements: 50 mm above, 32 mm in front, 10 mm below, 10 mm at the sides, zero behind.
