Schneider Electric 8502SCO4V02S Power Contactor

Schneider Electric Square D 8502SCO4V02S is a 5‑pole Type S vacuum contactor (size 4) with an open‑type enclosure designed to switch heavy three‑phase loads. It uses a 110/120 VAC coil and provides up to 135 A of load current, with a 100 HP rating at 575 VAC and a short‑circuit current rating up to 100 kA. This class 8502 contactor is intended for applications such as heating loads, capacitors, transformers, and electric motors where overload protection is provided separately; its 5‑pole configuration supports large three‑phase circuits in industrial controls and HVAC equipment. The device is designed for reliable operation in demanding environments and integrates with standard control circuitry to energize or de‑energize connected equipment.
