Square D 8903SPO3V02 60A 4-Pole Lighting Contactor 120V Coil Open Style

Overview This listing is for a genuine Square D 8903SPO3V02 Type S electrically held lighting contactor (Class 8903 series). Provides reliable switching for high-amp lighting circuits, ballasts, tungsten loads, resistive heating, or general-purpose applications up to 600 V. Compact open-style design (add enclosure as needed); supplied with 110/120 VAC 50/60 Hz interchangeable coil. Unit is brand new/unused surplus — in original factory box/packaging, pristine condition (never installed, includes all terminals/lugs as shown).

Key Features
