Square D 8903LO30V02 Lighting Contactor 3 Pole 30A

Product Description

The SQUARE D 8903LO30V02 is a 3-pole, electrically held lighting contactor designed for switching lighting loads in commercial and industrial electrical distribution systems. It operates at 30 amps for fluorescent loads and 20 amps for tungsten loads, with a control circuit voltage of 120 VAC at 60 Hz or 110 VAC at 50 Hz. The open, no-enclosure design makes it suitable for installation inside existing panelboards, switchboards, or custom enclosures where the installer provides the housing. The 3NO contact configuration keeps the circuit closed only while the coil is energized. Licensed electricians handle this type of installation as part of lighting control and load management work.

This contactor is applied in commercial buildings, parking structures, warehouses, and industrial facilities where centralized or automated switching of large lighting circuits is required. It fits into systems where an external control signal, timer, or energy management controller energizes the coil to switch the load. The open-style form factor is common in new panel builds and retrofit applications where an enclosure is already present. Its 3-pole design allows simultaneous switching of three-phase or multi-branch lighting circuits from a single device.

Key Features

• Electrically held operation — circuit stays closed only while coil remains energized
• 30-amp fluorescent rating and 20-amp tungsten rating for multi-load-type applications
• 3NO contact configuration for simultaneous three-pole switching
• Control circuit accepts 120 VAC at 60 Hz or 110 VAC at 50 Hz for broad system compatibility
• No-enclosure open design for installation inside existing panels or custom enclosures
• UL Listed, CSA certified, and RoHS compliant

Compatibility

Designed as an OEM-style replacement or new-installation lighting contactor for commercial and industrial lighting control panels requiring a 3-pole, electrically held, open-frame device rated for fluorescent and tungsten loads.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out all circuits before handling or mounting the contactor. Because this unit ships without an enclosure, the installer is responsible for providing a suitably rated enclosure that meets NEC requirements for the installation environment. Verify that the control circuit voltage source matches the coil voltage rating before energizing.
