Specifications
Withstand and Close-On Ratings for all 7000 Series Products
Notes: All values are available symmetrical RMS amperes and tested in accordance with the withstand and close-on requirements
of UL 1008. See publication 1128 for more information on withstand and close-on ratings for ASCO transfer switches.
Application requirements may permit higher withstand ratings for certain size switches (Contact ASCO).
* 150 amp 7000 Series in bypass-isolation configurations have higher WCR as indicated.

Non-Automatic Transfer Switching
ASCO Non-Automatic Transfer Switches are
electrically operated units which are operated with
manual control switches mounted locally or at
remote locations.
Fig. 4 Non-Automatic operated, electrically
operated 400 ampere switch shown in
Type 1 enclosure.
• Sizes from 30 through 4000 amperes.
• Microprocessor based controller
provides for addition of optional
accessories.
• Controller prevents inadvertent oper-
ation under low voltage conditions.
• Low control circuit operating cur-
rents allow for long line runs
between remotely mounted manual
control switches and the transfer
switch.
• Source acceptability lights inform
operator if sources are available to
accept load.
• Standard inphase monitor can be
activated for transferring motor
loads.
