Transfer Switch Equipment
Wall-Mount Automatic Transfer Switches
Mechanical Interlock
Triple Interlocks
Wall-mount transfer switches feature
a rear-mounted, patented fail-safe
mechanical interlock to prevent paral-
leling of sources. This is, in addition to,
software interlocking and the inter-
locking inherently provided by the
transfer mechanism.
Load Bus Assembly
Load Bus
The load bus can be oriented for either
top or bottom access.
Multi-Tap Voltage Selector
Multi-Tap Voltage Selector
The industry-exclusive Cutler-Hammer
Multi-Tap System Voltage Selector
allows our transfer switch to be applied
on most system voltages just by proper
insertion of the selector plug. Avail-
able in two configurations: Worldwide
Multi-Tap with 600, 480, 415, 380, 240,
220 and 208 Vac, single- and 3-phase,
50 and 60 Hz taps. North American
Multi-Tap with 600, 480, 240, 208 and
120 Vac, single- and 3-phase, 60 Hz taps.
Ease of Maintenance
Logic Disconnect Plugs
Keyed quick-disconnect plugs are pro-
vided for easy and complete isolation
of the control circuitry.
Maintenance can be performed on
the logic independent from the power
sections and still allow the user to
manually transfer power under full
load conditions.

comes with 600, 480, 240, 208 and
120 Vac, single- and 3-phase, and 60 Hz
taps which are all field selectable. Simply
remove the steel cover and move the
appropriate blue flag terminal to the
desired voltage. All switches are
shipped with the blue flag in the 600
volt position.
