SIRIUS 3RA2 non-fused motor starter, size S00
The Siemens 3RA2110-1HA15-1AP6 is a SIRIUS non-fused motor starter in size S00, combining a contactor and a thermal bimetallic overload relay in one unit for direct starting of three-phase motors. It ships with the 3RT2015-1AP61 contactor and the 3RA1921-1DA00 link module, so the assembly is matched from the factory — no separate component selection needed.
Motor power and current ratings across common voltages
At 480 V the starter is rated 3 hp and 4.8 A; at 600 V it delivers 5 hp and 6.1 A, covering the most common North American motor frames up to that size. For 50 Hz markets, the coil accepts 187…242 V at 50 Hz and 192…264 V at 60 Hz, so it works across the standard European and North American control voltages without a coil swap. Maximum AC-3 switching voltage is 690 V, matching the insulation rating of the S00 frame.
Class 10 trip and mounting flexibility
Mounting is snap-on to 35 mm DIN rail or screw-mount with an additional push-in lug, and the unit is rated for vertical installation only — plan the panel layout accordingly. Clearance requirements: 20 mm upwards, 10 mm downwards, and 9 mm at the sides — no extra space needed forwards or backwards, which helps in tight enclosures.
