Square D 8903LXG1200V02 Lighting Contactor 12 Pole

Product Description

The SQUARE D 8903LXG1200V02 is a mechanically held lighting contactor designed for switching lighting loads in commercial and industrial electrical distribution systems. It features a 12-pole configuration with 12 normally open contacts, rated at 20 amps for tungsten loads and 30 amps for fluorescent loads. The control circuit operates at 110 VAC at 50 Hz or 120 VAC at 60 Hz. Mechanically held operation means the contactor maintains its switched position without continuous coil energization, reducing energy draw on the control circuit. Licensed electricians are the primary installers of this device.

This contactor is suited for commercial lighting panel applications where multiple circuits must be switched simultaneously from a single control point. Typical installations include office buildings, warehouses, parking structures, and retail spaces where fluorescent or tungsten lighting loads require centralized, code-compliant switching. Its NEMA 1 enclosure rating makes it appropriate for indoor, dry locations. The 12-pole design allows control of up to 12 individual lighting branch circuits through one device.

Key Features

• Mechanically held design maintains contact position without continuous coil power
• 12-pole, 12 normally open contact configuration for multi-circuit lighting control
• Dual load ratings: 20 amps for tungsten, 30 amps for fluorescent loads
• Control circuit compatible with 110 VAC at 50 Hz and 120 VAC at 60 Hz
• NEMA 1 enclosure rated for indoor dry location installation
• CSA certified, UL Listed, and RoHS compliant

Compatibility

Designed as an OEM-style replacement or new-installation mechanically held lighting contactor for commercial and industrial lighting control panels requiring a NEMA 1 enclosed, 12-pole, 120 VAC control voltage device.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the panel before beginning any wiring work. Verify that the control circuit voltage source matches the contactor coil rating before applying power. Ensure the enclosure mounting surface is plumb and that all conductors are properly terminated and torqued per the terminal manufacturer specifications on the device label.
