Schneider Electric 8502SCO3V25 Four Pole Contactor

Schneider Electric Square D 8502SCO3V25 Four Pole Contactor is a Size 1 NEMA Type S open-type, nonreversing control device engineered to switch heavy loads in 3‑phase systems. It features four poles and a 110/120 VAC coil with screw-clamp terminals for secure wiring, designed for open installation with a compact footprint. The 8502SCO3 family provides a 27 A continuous current rating and supports up to 10 HP at 575 VAC, with a short-circuit current rating up to 100 kA (depending on system voltage and wiring). This contactor is intended for applications where overload protection is provided separately, such as motors, heating loads, transformers, or capacitors, and is compatible with 50/60 Hz control circuits. Its dimensions are a practical 4.25 in wide by 4.22 in deep by 4.33 in high, aligning with typical Size 1 form-factor installations in control panels and industrial equipment requiring reliable full-voltage switching.
