The Siemens SIRIUS 3RA2215-0FA15-2AK6 is a non-fused reversing motor starter in size S00, combining a contactor, thermal overload relay, and circuit-breaker into one assembly for forward/reverse motor control in a compact footprint. Rated for AC-3 duty up to 690 V and 50/60 Hz, the CLASS 10 trip class means it protects standard squirrel-cage motors during start-up without nuisance tripping on normal acceleration — a common spec for conveyor and pump reversing applications. Snap-mounted to DIN rail or screw-mounted with an additional push-in lug, this unit fits standard 90 mm wide panel slots and requires 170 mm vertical clearance plus 20 mm above and 10 mm below for wiring access.
It ships as a complete assembly with the supplied contactor (3RT2015-1AK62), link module (3RA1921-1DA00), and circuit-breaker (3RV2011-0FA15) — no separate component sourcing needed for the reversing function.
Integration Notes
Mounting position is vertical only; the thermal overload release (bimetallic) is calibrated for that orientation and may drift if mounted horizontally. Main contact wiring accepts 0.5 to 4 mm² stranded or 2x (0.75 to 2.5 mm²) — use ferrules on stranded wire to avoid whiskers under the cage terminals. Surge voltage resistance rated at 6 kV, suitable for industrial environments with pollution degree 3 — typical for panels near motors and drives without additional suppression.
