Eaton’s Superior Design Transfer
Switch Characteristics
Unmatched Performance
and Versatility
Eaton’s family of wallmount
transfer switches offers
unmatched performance,
versatility and value for
power switching applications.
At the heart of these designs
is Eaton’s molded case
switch, designed specifically
to meet UL 1008.
Superior Main
Contact Structure
All Eaton wallmount transfer
switches meet or exceed
the standards set forth in
UL 1008 and UL 489. No
other transfer switch
manufacturer has met the
rigid testing requirements
of this combination of
standards. Completely
enclosed contacts add a
measure of safety and
reliability. It also ensures
the integrity of the contact
assemblies and minimizes
the need for periodic
maintenance of the contacts,
reducing downtime.
Fast, Powerful and
Safe Power Switching
Mechanism
The power panel utilizes a
unidirectional
gear motor
mechanism. The power panel
can be operated manually
under a FULL LOAD.

Optional Integral Overcurrent
Protection Capability
For service entrance and
other applications, trip units
can be integrated into the
power switching section.
This eliminates the need
for separate upstream
protective devices, saving
cost and space.
