The Siemens 3RA2110-0HE15-1AP0 is a SIRIUS direct (on-line) starter in size S00, combining a contactor and overload relay in one assembly for motor starting and protection up to 180 kW at 400 V. It is a fuseless design — the overload relay provides motor protection without requiring separate fuses, simplifying panel wiring and reducing spare parts count.
Mounts via screw or snap-on onto 35 mm DIN rail in a vertical position, with 50 mm clearance upward, 20 mm forward, 20 mm at the side, 10 mm downward, and 0 mm backward — tight panel layouts need to respect these clearances for heat dissipation and arc flash. Dimensions are 97 mm deep, 45 mm wide, and 198 mm high, fitting into standard S00 feeder slots in Siemens SIRIUS distribution panels. Main circuit connections use spring-loaded terminals — no screw tightening needed, which speeds up panel wiring and reduces torque-verification steps.
Supplied components and ratings
The starter ships with a 3RT2015-2AP01 contactor and a 3RA2911-2AA00 link module pre-assembled — no separate ordering or matching required. Rated operational voltage is 690 V, with AC-3 switching at 400 V rated at 0.8 A and 180 kW at 400 V for the motor output.
It is a fast mover in the SIRIUS S00 line, widely stocked for panel builds and MRO spares across food-and-beverage, water, and HVAC plants.
