What this SIRIUS non-fused motor starter is
The Siemens 3RA2110-0AD15-1AK6 is a SIRIUS non-fused motor starter in size S00, designed as a direct starter with an electromechanical switching contact and a thermal bimetallic overload release (Class 10 trip class). It ships as a pre-assembled unit containing the 3RT2015-1AK61 contactor, the 3RA1921-1DA00 link module, and the 3RV2011-0AA10 circuit-breaker — three components that together form a coordinated motor feeder for a BOM line.
Trip class and overload protection — what Class 10 means on the line
For a motor starting a high-inertia load (conveyor, crusher, centrifuge) this is the tight window — if the acceleration time exceeds 10 seconds the starter will nuisance-trip before the motor reaches full speed. The magnetic short-circuit trip is separate from the thermal element, so a locked-rotor or phase-loss event clears on the magnetic side without waiting for the bimetallic strip to heat through.
Mounting and panel fit — snaps onto 60 mm busbar systems
The fastening method is for snapping onto 60 mm busbar systems — not a standard DIN rail mount. This is a busbar-mount motor starter, so the panel layout must accommodate the 60 mm busbar pitch and the vertical mounting position. Dimensions are 45 mm wide, 200 mm high, 155.1 mm deep. Clearance requirements: 20 mm upwards, 10 mm downwards, 9 mm at the side, and zero forwards or backwards.
Voltage and environmental ratings
The operating frequency range is 50 to 60 Hz. Pollution degree 3 means the unit is rated for industrial environments with conductive pollution or dry non-conductive pollution that becomes conductive due to condensation. Operating temperature range is -20 to +60 °C; storage range is -50 to +80 °C; transport range is -55 to +80 °C.
