The 3RA2110-1BE15-1AP0 is a Siemens SIRIUS direct online starter in size S00, combining a contactor and overload relay in one assembly for motor starting and protection. It is rated 750 kW at 400 V — this is the maximum motor power it can switch under AC-3 duty, so the connected motor must not exceed this figure. The 45 mm width and 97 mm depth (per the spec table) fit into a standard 45 mm-wide DIN slot — plan for this footprint when laying out the panel.
Supplied components and termination — what arrives in the assembly
The starter ships with the 3RT2015-2AP01 contactor and the 3RA2911-2AA00 link module pre-assembled. The main current circuit uses spring-loaded terminals — no screw tightening needed for the power wiring, which speeds up panel wiring and reduces the risk of loose connections under vibration. The operating temperature range is -20 to +60 °C with temperature compensation active across the same range, so the overload protection remains accurate in a warm enclosure or cold environment.
