Rated for 52 A at 480 V in AC-3 duty — that's the motor-switching current that governs real-world fit for pumps, fans, and compressors up to that load. The contactor handles 1 000 operations per hour in AC-1 resistive duty, 800 per hour in AC-3, and 250 per hour in AC-4 (plugging/inching).
Dimensions: 114 mm high, 55 mm wide, 174 mm deep. That 55 mm width matters for rail fill — it's a standard S2 footprint. Coil connection uses screw-type terminals. Main contact wiring accepts 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded copper.
That storage range is what the part sees in transit or in a hot warehouse — it's not a running condition.
