It carries a 27 A rating at 480 V AC-3 duty — that's the motor-switching current, so it handles a 3-phase induction motor up to roughly 15 kW at 480 V without derating. The screw-type coil terminals and integrated auxiliary switch (1 NO + 1 NC typical for this frame) simplify wiring in a standard panel layout.
The S0 footprint (45 mm wide, 85 mm high, 97 mm deep) is a common size across the SIRIUS contactor family, making panel cutouts and busbar layouts predictable.

Rated 27 A at 480 V AC-3 for motor switching, Size S0 frame, screw-type coil terminals, auxiliary switch included, operating temperature -25 to +60 °C, DIN rail mount.
Both are Size S0 contactors on the same 45 mm DIN-rail footprint, so the physical mounting and busbar positions are identical. However, verify the coil voltage and auxiliary contact configuration on the order code suffix — the 3RT2036-1AC20-ZX95 may carry a different coil rating or auxiliary arrangement, so check the nameplate against your panel schematic before swapping.
