New Allen-Bradley Lighting Contactor From Rockwell Automation Designed for Branch Circuits, Saves Energy
MILWAUKEE, July 25, 2005 - To help manufacturers reduce energy consumption, Rockwell Automation introduces the Allen-Bradley Bulletin 500LC Lighting Contactor, a multi-pole lighting contactor designed for branch circuits.
Because the Bulletin 500LC Lighting Contactor controls a specific number of branch circuits, or luminaries, rather than large blocks of lighting, it gives building designers greater design flexibility and customization options.
Mechanically held lighting contactors, like the Bulletin 500LC Lighting Contactors, do not change position and disconnect lights during a drop, reduction or loss of voltage. Because the Bulletin 500LC Lighting Contactor only requires a momentary applied current - 20 amps - to either open or close and is not dependent on a continuous control voltage to maintain its position, it also is more energy efficient than electrically held contactors which require a constant stream of electricity.
The Bulletin 500LC Lighting Contactor is easy to install in both new and retrofitted environments. It has the same interruptible rating as UL 67 listed panelboards, the same small footprint for two-, six- and 12-pole contactors, and mounts with only four screws. Its size remains the same, regardless of the number of inputs/outputs. Panel builders can install it within or next to an enclosure, and additional inputs/outputs are on the front for easy access.
For flexibility, users can control the Bulletin 500LC Lighting Contactor from multiple sources, including manually operated contact switches, auxiliary relays, solid-state modules, timers with single- or double-throw contacts, and energy management systems. The Bulletin 500LC Lighting Contactor can connect with various control systems and devices, such as energy management systems, microprocessors, photoelectric cells and timers. As a solid-state module, it also can have 2-wire, 3-wire and start/stop control to allow it to interface with remote objects, like human-machine interfaces.
For electrical contractors seeking energy-efficient contactors for low-noise environments, the Bulletin 500LC Lighting Contactor may be ideal. Because the contactor's operating coil is not continuously energized, coil hum and continuous coil consumption is eliminated. This reduces irritating background noise and saves energy at the same time.
The Bulletin 500LC Lighting Contactor, which is available through authorized Allen-Bradley distributors, is UL 508 listed, CSA certified and suited for UL 67 listed panelboards.
