Critical Loads Demand ASCO
As we become more dependent on the quality and
reliability of electrical power,
interruption or complete loss
of power can create serious
and even crippling financial
losses, or impose dangers to
life and safety.
ASCO Power Technologies
(ASCO) provides the solutions to handle the transfer
of critical loads to emergency sources reliably and
with state of the art products. Using ASCO products
can mean the difference
between a minor inconvenience and a major catastrophe. You’ll find ASCO Power
Transfer Switches wherever
there is a critical load to be
protected.
When flexibility in power
switching is a must, ASCO
offers a variety of product
solutions to meet virtually
every application requirement, including distributed
generation applications.
That’s why the 7000 SerieS
is available in open, delayed,
closed and closed soft load
configurations. Additionally,
switched or overlapping
neutral options provide for
reliable operation of ground
fault protection systems and
reduction of voltage transients from unbalanced load
switching.

The Recognized Leader in Power Transfer
Switch Technology Offers the Most
Advanced Transfer Switches in the World.
7000 series
ASCO Power Transfer Switches are the standard of the
industry. High speed transfer of loads between alternate sources of power, regardless of ampacity size, is
achieved by a reliable, field proven solenoid operating
mechanism. When combined with a programmable
microprocessor controller with keypad and LCD display,
they offer the most advanced method of transferring
all types of loads, such as motors, electronic drives,
UPS’s and microprocessor based systems. 7000 SerieS
Power Transfer Switches are available open or enclosed,
in ampacity sizes from 30 through 4000 Amperes with
the largest selection of optional accessories offered anywhere. All switching configurations are available with an
integrally mounted bypass-isolation switch and/or rated
for use in service entrance applications.

7000 series Power Switching Solutions
Closed Transition Transfer Switching
ASCO Automatic Closed Transition Transfer Switches feature
main contacts that overlap, permitting the transfer of electrical
loads without power interruption. The switch transfers in a
make-before-break mode if both sources are within acceptable
parameters. Control logic continuously monitors source
conditions and automatically determines whether the load
transfer should be open (conventional non-overlap mode) or
closed transition. Available 150 through 4000 Amperes.
Closed Transition Transfer within 5 electrical degrees is achieved
passively, without control of engine generator set. Therefore,
no additional control wire runs are required between the ATS and
engine generator set governor. Plus, protective relaying may
not be required under normal operation since the contact overlap time is less than 100 milliseconds (consult your local utility
on protective relay requirements).
Failure to synchronize indication and extended parallel time
protection is built-in to all 7000 SerieS closed transition
controls to prevent abnormal operation.
Fig. 2: Four pole, Closed Transition Transfer Switch
rated 1000 Amperes in Type 1 enclosure.
Delayed Transition Transfer Switching
ASCO Delayed Transition Transfer Switches are designed
to provide transfer of loads between power sources with a
timed load disconnect position for an adjustable period of
time. Applications include older style variable frequency
drives, rectifier banks, and load management applications.
• Available in 150 through 4000 Amperes.
• Utilizes reliable, field proven solenoid operating
mechanisms.
• Mechanical interlocks to prevent direct connection
of both sources.

Power Control Center.
12
The 7000 SerieS microprocessor controller is a Power Control Center which
allows the user to easily access detailed information on: system status; power
source parameters; voltage, frequency and time delay settings; optional
feature settings; historical event log; and system diagnostics. A four line,
(20) character LCD has a backlit display which enables easy viewing under all
conditions. The user can navigate through all screens using only six buttons,
which also allows selection of: (18) different source parameter settings; (16)
standard time delays; (12) standard feature settings; up to seven independent
engine exercise routines; and even the language (English, German, Spanish,
French, etc.) which appears on the display.
Since the Power Control Center must be visible and operable through
the enclosure door, it has been qualified for use in industrial and outdoor
applications. This includes installation in Type 3R (outdoor/rainproof),
4 (weatherproof) and 12 (indoor/industrial) enclosures. For applications with
regular exposure to direct sunlight a double door for UV protection is recommended.
