It is rated 27 A at 480 V in AC-3 duty (motor switching) and 5 hp at 230 V, so it handles typical three-phase motors up to that horsepower without derating. The contactor includes an auxiliary switch block, saving a separate add-on for basic status feedback.
The S0 footprint — 45 mm wide, 102 mm tall, 97 mm deep — fits standard panel layouts; the 45 mm width matches a single 9 mm module pitch multiplied by five, so it occupies five adjacent slots on the rail.
AC-3 rated 27 A at 480 V means this contactor can switch a three-phase motor drawing 27 A under full-load starting conditions — the typical duty for conveyors, pumps, and compressors. For high-inertia loads or plugging duty (AC-4), the maximum switching rate drops to 250 operations per hour, so it is not intended for frequent reversing or jogging applications.
