All 641 Lighting Con­trol Panel components are
factory wired and tested to
help ensure proper system
operation and long-term reli­ability. Integrating compo­nents into a single enclosure
eliminates the need to order
from multiple manufacturers
and the scheduling, billing
and multiple contacts that
requires.

standards. In fact, certain
lighting contactors are UL
listed for short circuit with­stand current ratings.

The panel also is fully
documented to ease trouble­shooting, if ever necessary.
It’s based on ASCO’s 100­year tradition of applied
technology and the quality
assurance that’s designed
into every ASCO product.

The 918 Lighting Contactor Is the Heart of the 641 Lighting Control Panel

The ASCO 918 Remote
Control (RC) Lighting Contac­tor is the heart of the ASCO
641 Lighting Control Panel.

It provides reliable and

Distinguishing Features

convenient lighting control
in a variety of applications.
It is rated at 30 amperes to
600 volts AC and is listed to
UL 508.

Solid-state control mod­ules enable energy manage­ment systems, microproces­sors, photoelectric cells,
timers and similar control
devices to manage the light­ing contactor.

A Range of Lighting
Control Applications

Performance Features

• 3 standard models to choose from

• Feature ASCO 918 RC Contactors. (electrically operated,
mechanically held, designed for lighting applications)

• Quieter operation (no AC hum)

• Longer life expectancy for contactor

• Fully rated for all types of lighting loads, including metal
halide, mercury vapor, quartz halogen, tungsten, and uo­rescent

Construction Features

• All controls, except for photocell, in common Type 1 enclo­sure (Type 12, 3R, 4, and 4X enclosures are available)

• Available in 6 or 12 pole design

• ASCO 918 visual position indicators show open/closed
position of each main contact

• ASCO 918 line, load, and control terminals accept no. 18 to
no. 10 AWG wire

• Large dial, multifunction 7-day timer with reserve power
feature or digital time clock with battery backup (Models
641A, 641 S)

• Clamp-type, self-rising terminal plates for solderless con­nection with the screws for fast termination

Electrical Features

• Available 120 or 277 V, 60 Hz control

• All control wiring stranded #14 AWG

• UL 1015 Red wiring

• Terminal block for all incoming wiring

• Fused power circuit

• UL Listed to UL508 Industrial Controls

• Rated 20 amps to 600 VAC (30 amps general purpose)

• Fully rated for all types of lighting loads

• High withstand current ratings

The lighting control
panel is ideally suited for
ballast lighting, tungsten
and general-purpose loads.
The ASCO 641A Lighting
Contactor Panel satises
requirements of large-area
applications. 641S meets
requirements for security ap­plications and 641 AS meets
requirements for both.

Applications include
large areas, stadium park­ing garages and facilities
using TOD (Time of Day)
photo-sensor control for
automatic on-off operation.
Other applications are signs,
interior and exterior build­ing lighting, interior safety
lighting, recreational lighting
and applications suitable for
manual on-off operation.

The 641 Lighting Control
Panel is available in standard
and highly customized con­gurations. Three standard
congurations offer quicker
delivery, while customized
congurations offer the ex­ibility to tailor performance
to site-specic requirements.

Standard panels feature the
ASCO 918 Lighting Contac­tor that’s based on ASCO’s
electrically operated, me­chanically held solenoid
operator that also is the heart
of all ASCO power transfer
switches.

The solenoid does not rely
on magnetic latches or
impressed current to main­tain contacts in the open or
closed position. The contac­tor offers quieter operation,
longer life expectancy and
eliminates the continuous
power drain associated with
electrically held solenoid
designs.

This contactor is specically
designed for metal halide,
mercury vapor, quartz halo­gen, tungsten and uores­cent lighting systems.

Custom Configurations

Custom congurations for
comprehensive lighting con­trol requirements can include
up to 10 lighting contactors
in one enclosure, in addition
to related controls and acces­sories.

Besides the 918 Lighting
Contactor, the panel also
is available with the 920
Lighting Contactor. Panels
congured with 920 Light­ing Contactors become the
ASCO 642 Lighting Contactor
Panel.

Controls and accessories can
include relays, building man­agement interfaces, time
clocks, photocell interfaces,
pilot lights, control switches,
power fusing, and other func­tionalities.
