Reversing starter in SIRIUS S00 frame
The Siemens 3RA2215-1EA15-2AP6 is a reversing motor starter in the SIRIUS family, Size S00 frame — the compact footprint for load feeders up to 690 V AC-3. This is a non-fused design, meaning it relies on an upstream circuit breaker for short-circuit protection rather than integral fuses. It ships as a factory-assembled unit including the 3RT2015-1AP62 contactor and the 3RA1921-1DA00 link module, saving panel-build time over sourcing components separately.
Class 10 thermal overload and AC-3 duty
At 400 V AC-3 duty the starter is rated for 1.5 kW motor load; at 480 V it handles 3.95 A, and at 600 V 4 A — the current ceiling is consistent across the upper voltage range, limited by the S00 contactor thermal capacity rather than arc extinction.
DIN rail snap-on with clearance for reversing
The 90 mm width and 170 mm height fit a standard S00 cavity; depth is 97.1 mm including the contactor coil projection. Side clearance of 9 mm allows adjacent starters without thermal derating. Main contact wiring accepts stranded conductors 0.5–4 mm², or two conductors 0.75–2.5 mm² in parallel — flexible enough for mixed control and power circuits in a panel.
Active production — current lifecycle stage
Operating temperature range is -20 to +60 °C with storage from -50 to +80 °C — suitable for unheated industrial enclosures across most climate zones. Pollution degree 3 per IEC 60947-1 means it tolerates conductive dust and condensation typical of factory-floor control panels without conformal coating.
