Tr a n s f er Switches
Standard and Optional Features
Transient Voltage Surge
Suppression
Eaton’s Clipper Power
System —Visor™ series
transient voltage surge
suppression (TVSS)
components can be
integrated into any closed
transition soft load switch.
Surge current ratings 100 kA,
160 kA and 200 kA per phase
provide a range of cost-
effective
facility-wide
protection solutions. Status
indication on each phase is
standard with any TVSS
option. Metering and
communication capabilities
are also available. See
Appendix C for details.
Communications
Optional communication
capability via Communication
Gateway is available, allowing
remote data access, control,
programming, system
interface and dispatch.
System Interface
A system control panel
provides a user-friendly
interface to the closed
transition soft load controller,
allowing operators to easily
monitor the switching
devices position and manually
test
the generator and the
system operations.

Optional Intergral Overcurrent
Protection Capability
For service entrance
applications, Digitrip
microprocessor-based trip
units can be integrated into
the power switching devices.
This eliminates the need for
the separate upstream
protective device, saving
installation cost and space.
Available with various
combinations of long, short,
instantaneous and ground
fault protection, Digitrips
can communicate with
Eaton’s IMPACC and
PowerNet Power
Management Systems.
Optional On-Board 24 Vdc
Power Supply
On-board 24 Vdc power
supply circuit, consisting of
two 12 Vdc gel-cell UPS type
batteries and battery charger,
is available on the unit to
provide DC control power
to soft load transfer switch
components. Engine battery
can be connected in the
“best battery” circuit as
well, further improving the
system’s reliability.
