Square D 8903SPO1V02 Lighting Contactor 60A 2 Pole

Product Description

The SQUARE D 8903SPO1V02 is a 2-pole, electrically held lighting contactor rated for 60 amps (Tungsten load) and designed for switching lighting circuits in commercial and industrial electrical systems. The open construction means it ships without an enclosure and must be installed inside a suitable panel, switchboard, or field-supplied enclosure. Control circuit voltage is 110 VAC at 50 Hz or 120 VAC at 60 Hz. Licensed electricians install this device as part of a lighting control scheme, relay panel, or energy management system where remote or automatic switching of high-wattage lighting loads is required.

This contactor is suited for commercial buildings, warehouses, parking structures, and industrial facilities where large banks of incandescent, fluorescent, or HID lighting must be switched from a central control point. Electrically held operation means the coil must remain energized to keep the contacts closed, which provides a built-in fail-off safety behavior if control power is lost. The open-style design allows integration into custom enclosures or existing panel assemblies where space and layout are determined by the installer.

Key Features

• 60-amp Tungsten-rated contacts for reliable switching of incandescent and resistive lighting loads
• Electrically held design drops load if control voltage is lost
• Dual-frequency coil: 110 VAC at 50 Hz and 120 VAC at 60 Hz
• 2-pole configuration for single-phase lighting branch switching
• Open construction for integration into field-supplied or existing enclosures
• CSA certified, UL Listed, and RoHS compliant

Compatibility

Designed as an OEM-style replacement or new-installation electrically held lighting contactor for commercial and industrial lighting control panels requiring a 2-pole, 60-amp open contactor with 120 VAC coil voltage.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the NEC and all applicable local codes. De-energize and lock out all control and load-side power before handling or wiring the contactor. Because this unit ships without an enclosure, it must be mounted inside a listed enclosure with appropriate short-circuit protection and wire terminations. Verify coil voltage matches the control circuit before energizing.
