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.
• Sizes from 30 through 4000 amperes.
• Microprocessor based controller provides for addition
of optional accessories.
• Controller prevents inadvertent operation under low
voltage conditions.
• Low control circuit operating currents 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.
