|New Allen-Bradley Lighting Contactor From Rockwell Automation Designed
for Branch Circuits, Saves Energy|
MILWAUKEE - 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
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.
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.
