Unmatched Performance
and Versatility
The Eaton family of Magnum
transfer
switches offers
unmatched performance,
versatility and value for
standby power applications.
At the heart of these designs
is the Magnum switch with
the following features:
Superior Main
Contact Structure
All Eaton Magnum Transfer
Switches meet or exceed
the standards set forth in
UL 1008 and UL 489 with
high withstand, totally
enclosed Magnum switches.
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. They also ensures
the integrity of the contact
assemblies and minimizes
the need for periodic
maintenance of the contacts,
reducing downtime and
maintenance time.
Fast, Powerful and Safe
Switching Mechanism
The mechanism utilizes a
high speed ≤ than 3-cycle
stored energy switching
mechanism. This mechanism
can be operated manually
under a FULL LOAD.
Ease of Coordination
and Application—
Short-Time Withstand
The use of electronic trips
has allowed performance
curve shaping to facilitate
proper system coordination.
The most significant is the
“short time” rated trip unit.
These trip settings may be
set for what are considered
extremely high currents for
much longer durations than
the three-cycle withstand
test required under UL 1008.
To facilitate improved
coordination, Eaton Magnum
transfer switches have been
tested and are provided with
30-cycle, extended withstand
ratings.
Magnum Power Case Switch
Optional Integral
Overcurrent Protection
Capability
Optional Digitrip
TM
Magnum Trip Unit
Service Entrance
For service entrance and
other applications, Digitrip
solid-state trip units can be
integrated into the power
switching section. This
eliminates the need for
separate upstream protective
devices, saving cost and
space. Available with various
combinations of long, short
time, instantaneous, ground
fault protection and
communications.
