ASCO Automatic Transfer Switches are the
standard of the industry. High speed transfer of
loads between alternate sources of power, regard-
less of ampacity size, is achieved by a reliable,
field proven solenoid operating mechanism.
When combined with a programmable micro-
processor controller with keypad and LCD
display, it offers the most advanced method of
transferring all types of loads, such as, motors,
electronic drives, UPS’s and microprocessor
based systems. It is the only true double throw,
inherently interlocked transfer switch in the
industry and is available in ampacity sizes
from 30 through 4000 amperes. 7000 Series
automatic transfer switches are available open or
enclosed, with the largest selection of optional
accessories offered anywhere.
• Front replaceable main and arcing contacts
(600-4000 amperes).
• Programmable microprocessor controller with
keypad and LCD display.
• Centrally located terminal block for customer
control connections (260-4000 amperes).
• Heavy-duty, 16mm, industrial grade control
switches and indicating lights.
• Switch position indicators and true source
acceptability lights.
• Standard ground lug or ground bus connection.
• Four auxiliary contacts, two contacts closed
when switch is in normal position and two contacts
closed when switch is in emergency position.
• Local/remote serial communications capability
for interfacing with ASCO PowerQuest products.
