The Allen-Bradley Bulletin 500LC from Rockwell Automation is a 20 A multi-pole lighting contactor designed for branch circuits. Because the unit controls a specific number of branch circuits, or luminaries, rather than large blocks of lighting, it provides flexibility and customization options. As a mechanically held lighting contactor, it disconnects lights during a drop, reduction or loss of voltage. The unit only requires a momentary applied current to either open or close and is not dependent on continuous voltage to maintain its position.
