Panel fit and mounting — S00 frame on DIN rail
The 3RA2115-4AA18-1AK6 is a non-fused motor starter from the SIRIUS 3RA2 family, size S00. Mounting position is vertical. Clearance needs: 20 mm upward, 10 mm downward, 9 mm at the sides, zero forward or backward — useful for tight panel layouts where gland plates or busbars limit space.
Motor duty and trip class — what the ratings mean
At 400 V AC-3 duty it handles 7.5 kW (10 hp); at 460/480 V it handles 10 hp, and at 575/600 V also 10 hp. The supplied contactor is a 3RT2018-1AK61, and the link module is 3RA1921-1DA00 — the starter ships as a matched assembly, not loose components.
Environmental range and pollution tolerance
Operates from -20 to +60 °C ambient; stores from -50 to +80 °C and survives transport from -55 to +80 °C. Pollution degree 3 means it tolerates conductive dust and condensation typical of industrial enclosures without conformal coating.
