Square D 8903LO1200V02 12 Pole Lighting Contactor

Product Description

The SQUARE D 8903LO1200V02 is a 12-pole, electrically held lighting contactor designed for controlling large lighting loads in commercial and industrial electrical distribution systems. It carries a 20-amp rating for tungsten loads and a 30-amp rating for fluorescent loads. The coil operates at 110 VAC at 50 Hz or 120 VAC at 60 Hz, making it suitable for standard North American and some international control circuit configurations. The open, no-enclosure construction means this contactor is intended for installation inside a separately specified enclosure or panelboard. Licensed electricians perform installation in accordance with applicable NEC requirements.

This contactor is used in commercial, institutional, and industrial lighting control applications where centralized switching of multiple circuits is required. Typical installations include office buildings, warehouses, parking structures, schools, and retail facilities where multiple lighting branch circuits must be switched simultaneously. The 12-pole configuration allows a single contactor to control up to 12 separate circuits. The electrically held design maintains contact closure as long as the control circuit remains energized, which is standard for time-clock, photocell, and building automation system control schemes.

Key Features

• 12 normally open (12NO) contact configuration for simultaneous multi-circuit control
• 20-amp tungsten load rating and 30-amp fluorescent load rating per pole
• Control coil rated at 110 VAC at 50 Hz and 120 VAC at 60 Hz
• Electrically held operation compatible with time-clock, photocell, and BAS control inputs
• Open construction for integration into a customer-supplied enclosure or panel
• CSA certified, UL Listed, and RoHS compliant

Compatibility

Designed as an OEM-style replacement or new-installation lighting contactor for open-type commercial and industrial lighting control panel assemblies requiring a 12-pole, electrically held device with a 120 VAC control circuit.

Installation Notes

Installation must be performed by a licensed electrician in compliance with the National Electrical Code (NEC) and all applicable local codes. De-energize all circuits at the panel before handling or wiring the contactor. Because this unit ships without an enclosure, it must be mounted within a suitable rated enclosure that provides adequate protection for the installation environment. Verify that the control circuit voltage matches the coil rating before energizing.
