Schneider Electric Square D 8502SBO2V02S Contactor

Schneider Electric's Square D 8502SBO2V02S is a NEMA Type S, nonreversing, three-pole contactor (Size 0) with a 120 VAC coil, designed for three-phase motor and inductive-load control in industrial panels. It is rated for 18 A (continuous) and up to 5 HP at 575 VAC, with a short-circuit current rating up to 100 kA, making it suitable for demanding line-side switching. This open-type device features a 3 Form A (NO) configuration, providing three normally-open contacts for straightforward control wiring, and carries Trade Agreements Act (TAA) compliance for government and broader procurement. The 120 VAC coil enables integration with standard low-voltage control circuits, while the Size 0 footprint supports compact panel layouts; typical applications include motor control, capacitors, transformers, and heating loads where overload protection is provided separately.
