Square D 8502SFO2V02S Push Button Station NEMA 4

Square D 8502SFO2V02S is a three-pole, size-4 motor contactor from Schneider Electric’s Square D line, intended for 3‑phase motor control in environments protected to NEMA 4 when mounted in a suitable enclosure. It uses a 120 VAC control coil to switch 3‑phase loads up to 135 A, with a horsepower rating of 100 HP at 575 VAC. This non‑reversing contactor (Type S) offers three main contacts in a 3P configuration and is rated for a short‑circuit current up to 100 kA, depending on system conditions. The part number 8502SFO2V02S identifies this device within the 8502S family of contactors and is widely cataloged with a 120 VAC coil, 3P, 135 A, and 100 HP at 575 VAC for industrial motor control. Typical applications include start/stop control for large motors in pumps, conveyors, fans, and HVAC equipment, where reliable remote switching is required in coordination with overload protection. For use in harsh environments, pair the contactor with a compatible enclosure that meets the NEMA 4 standard. In short, 135 A, 120 VAC coil, 3P, 3‑pole, 575 VAC HP rating 100, NEMA 4, non‑reversing, part number 8502SFO2V02S.
