The 3RA2210-0HA15-2AP0 is a Siemens SIRIUS reversing starter, size S00 — a pre-assembled combination of a contactor and overload relay in one package that swaps motor rotation direction. It comes with the supplied contactor 3RT2015-1AP02 and link module 3RA1921-1DA00, so you're not piecing together separate parts for forward/reverse control.
Mounting and panel fit — DIN rail or screw, vertical only
The mounting position is vertical — that's not optional; the overload relay's thermal calibration assumes upright orientation for proper heat dissipation. Dimensions: 97 mm deep, 90 mm wide, 170 mm tall. Clearance requirements: 50 mm upward, 32 mm forward, 10 mm downward, 10 mm at the side, and zero backward. That zero backward clearance means the back of the unit can sit flush against the panel wall — useful when you're packing components into a shallow enclosure.
Environmental range and storage — what it can handle
Operates from -20 to +60 °C, with storage and transport tolerance from -50 to +80 °C. That -20 °C low end matters if the panel sits in an unheated warehouse or outdoor cabinet; the -50 °C storage limit covers cold-weather shipping without damage.
