Mounting position is vertical only; the 20 mm clearance above and 10 mm below are the minimum free air gaps for the bimetallic overload to track ambient temperature correctly. ## Motor protection and trip coordination Thermal bimetallic design, no electronic adjustment drift over temperature; the overload release is self-powered and does not draw from the control circuit. ## Supplied components and wiring Ships with the 3RT2015-1AK61 contactor and the 3RA1921-1DA00 link module pre-assembled — no separate ordering of contactor and overload, and the link module handles the power bus between them. ## Environmental and compliance range Operates from -20 to +60 °C ambient; storage range is -50 to +80 °C, transport range -55 to +80 °C — the wider transport window matters for unheated freight in winter. Pollution degree 3 rating means it is suited for industrial enclosures where conductive dust or occasional condensation is present, not just clean control rooms.","metaTitle":"Siemens 3RA2115-1FA15-1AK6 SIRIUS Motor Starter","metaDescription":"Siemens 3RA2115-1FA15-1AK6 SIRIUS non-fused motor starter, 3 hp at 460/480 V, Class 10 thermal overload.
