Schneider Electric’s Square D 8903SQO11V02 Lighting Contactor is a Type S, mechanically held, 100 A, 3-pole device designed to switch lighting circuits. It uses a 110/120 VAC coil operating at 50/60 Hz and comes in an open-style enclosure with TAA compliance for government and other procurement needs. Rated to switch up to 600 VAC on the load side, this contactor provides reliable, maintained-state control for lighting applications where the coil can latch in the on position without continuous energization.
