The Siemens 3RA1110-0GA15-1AM2 is a non-reversing combination starter — a single package that integrates a contactor, overload relay, and short-circuit protection coordination for a motor branch circuit. It mounts on a DIN rail or panel, uses the SIRIUS S00 frame size, and is rated for 0.45-0.63 A with a 240 VAC control voltage. The contactor carries one normally open auxiliary contact; the motor starter protection (MSP) auxiliary is not fitted. The 0.45-0.63 A setting range governs the overload protection for the connected motor. That means this starter is sized for fractional-horsepower IEC motors — small pumps, fans, or conveyor drives in the sub-kilowatt band. The 240 VAC coil matches standard North American and European control voltages, so it drops straight into a panel with a 240 V control transformer. Because it is a combination starter, the 3RA1110-0GA15-1AM2 saves panel space and wiring time versus assembling a separate contactor, overload, and fuse holder. The SIRIUS S00 frame keeps the footprint compact — about 45 mm wide on the DIN rail.
Sourcing is straightforward.
The 3RA1110-0GA15-1AM2 is designed for DIN-rail or panel mounting. The SIRIUS S00 frame means it fits alongside other S00 devices — contactors, overloads, and auxiliary blocks — in a tight enclosure. Panel builders should account for the 45 mm width per unit and leave clearance for wiring the 240 VAC control circuit and the motor load cables. If more auxiliaries are needed, the SIRIUS S00 platform accepts clip-on auxiliary contact blocks — no tools required.
