Square D 8903LXO1200V02 Lighting Contactor 12 Pole

Product Description

The SQUARE D 8903LXO1200V02 is a mechanically held lighting contactor designed for commercial and industrial lighting control applications. It features a 12-pole configuration with a 12NO contact arrangement, 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. Supplied without an enclosure, this unit is intended for installation inside an existing panel, switchboard, or customer-supplied enclosure. Licensed electricians perform this type of installation as part of branch-circuit lighting control systems.

This contactor is suited for commercial lighting panels in office buildings, retail spaces, warehouses, and similar facilities where multiple lighting circuits require centralized switching. The mechanically held design holds the contactor in its last energized position without continuous coil power, making it well suited for energy-management and building-automation control schemes. The open construction allows integration into custom enclosures or existing electrical infrastructure where space and layout are predetermined.

Key Features

• Mechanically held operation holds position without continuous coil energization, reducing heat and energy draw at the coil
• 12-pole, 12NO contact configuration allows simultaneous switching of up to 12 lighting branch circuits
• Dual amperage rating: 20A for tungsten loads and 30A for fluorescent loads
• Control circuit voltage of 110 VAC at 50 Hz and 120 VAC at 60 Hz for broad compatibility with North American and international control systems
• Open construction with no enclosure for integration into panels or custom assemblies
• UL Listed, CSA certified, and RoHS compliant

Compatibility

Designed as an OEM-style replacement lighting contactor for commercial and industrial lighting control panels requiring a 12-pole mechanically held open-frame unit with 110 to 120 VAC control voltage.

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 circuit before mounting or wiring this contactor. The open design requires mounting within a suitable enclosure that provides adequate protection per NEC requirements. Verify that the control circuit voltage source matches the rated coil voltage before energizing.
