The Siemens 3RA1110-1AA15-1AT6 is a nonreversing combination starter from the SIRIUS family, frame size S00, rated for 1.1-1.6 A with a 277 VAC control voltage. It integrates a motor starter protector (MSP) and a contactor in one unit, saving panel space and wiring compared to separate components. The contactor carries one normally open auxiliary contact; the MSP has no auxiliary contacts fitted. The 1.1-1.6 A setting covers small motor loads — think fractional-horsepower pumps, fans, or conveyors — where you need coordinated overload and short-circuit protection in a single package.
