All Magnum switching devices are 100% rated, Underwriters Lab- oratories (UL) listed, and are built and tested in an ISO 9002 certi- fied facility to applicable NEMA, ANSI, IEEE, and UL standards.

For more information on Magnum switching devices, consult the Magnum switching device manual supplied with the transfer switch.

The main difference between the fixed and drawout versions of the Magnum switching devices used in the Magnum transfer switch is the mounting method. Fixed switching devices are bolted directly into the transfer switch frame while drawout switching devices are mounted in an extendable carriage within the transfer switch, allowing the switching device to be “drawn out” for service, maintenance, and/or replacement.
