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.
