The Siemens 3RA2110-1ED15-1AP0 is a SIRIUS direct on-line starter — a pre-assembled combination of a contactor and overload relay in one compact unit, size S00, designed to start and protect three-phase motors up to 3 hp at 460/480 V. It is rated for Type of Coordination 2, meaning that under a short-circuit fault the starter remains serviceable after clearing the fault — no replacement of the contactor or overload relay required, only a check of the settings.
This starter snaps directly onto 60 mm busbar systems — no DIN rail adapter needed — saving panel space and busbar drilling time. Mounting dimensions: 203 mm height, 45 mm width, 155 mm depth, with clearance requirements of 50 mm upwards, 20 mm forwards, 20 mm at the side, 10 mm downwards, and 0 mm backwards.
Coil and Control Voltage
The supplied contactor is a 3RT2015-1AP01; the supplied link module is a 3RA1921-1DA00 — both factory-integrated and tested as a matched set.
