Tr a n s f er Switches
Breaker-Based Designs
Mechanical Interlock
Wallmount transfer switches
feature a rear-mounted,
patented fail-safe mechanical
interlock to prevent paralleling
of sources. This is, in addition
to software interlocking and
the interlocking inherently
provided by the transfer
mechanism.
Triple Interlocks
Load Bus Assembly
The load bus can be oriented
for either top or bottom
access. Top entry is standard.

Multi-Tap Voltage Selector
Eaton’s industry-exclusive
Multi-Tap system voltage
selector allows our transfer
switch to be applied on most
system voltages just by proper
insertion of the selector
plug. Available in two
configurations: Worldwide
Multi-Tap with 600, 480, 415,
380, 240, 220 and 208 Vac,
single- and three-phase,
50 and 60 Hz taps. North
American Multi-Tap with
600, 480, 240, 208 and
120 Vac, single- and three-
phase, 60 Hz taps.

Ease of Maintenance
Keyed quick-disconnect
plugs are provided 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.

North American
Voltage Selector
North American multi-tap
transformer comes with 600,
480, 240, 208 and 120 Vac,
single- and three-phase, and
60 Hz
t aps, 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 600V
position.
