Dimensions are 97 mm deep, 45 mm wide, and 167 mm high — the 45 mm width fits a standard 45 mm-wide DIN-rail footprint, leaving room for adjacent devices in a crowded panel. The supplied contactor is a 3RT2015-1FB41 and the link module is a 3RA1921-1DA00 — these are the specific matched components inside the starter assembly, so replacement or spare ordering is straightforward.","metaTitle":"Siemens 3RA2110-0KA15-1FB4 SIRIUS Motor Starter","metaDescription":"Siemens SIRIUS 3RA2110-0KA15-1FB4 direct-on-line motor starter, 370 kW at 400 V, Class 10, screw/snap-on DIN rail.
