Designed to Fit Anywhere
The ASCO Automatic Transfer Switch, 300 series line represents the most compact design
ofÂ automatic power transfer switches in the industry. With space in electricalÂ closets being
at a premium, the use of wall or floor mounted ASCOÂ Transfer Switches assureÂ designers
optimum utilization of space.Â All transfer switches through 2000 amperes areÂ designedÂ to
be completely frontÂ accessible; permitting the enclosures to be installed flushÂ againstÂ the
wallÂ while allowing installation of all power cabling and connections from theÂ frontÂ of the
switch.Â Additionally, cable entrance plates are also standard on the 1600 andÂ 2000Â amperes
units toÂ install optional side-mounted pull boxes for additional cableÂ bending space.
