The Schneider Electric 8903-LXO30 Square D lighting contactor switches up to three lighting circuits at 20 amps using a 120-volt coil. Electricians mount the open-style unit in panels or enclosures to control banks of fluorescent, HID, or incandescent fixtures from a central location or automation system. Its electrically held design maintains contact position only while the coil is energized, suiting applications where automatic or timed lighting control is required.
