Transfer Switch Equipment
Transfer Switch — Optional Components
Transient Voltage Surge Suppression
Eaton's Clipper Power System —
Visor series transient voltage surge
suppression (TVSS) components can
be integrated into any closed transi-
tion 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 user-
friendly interface to the closed transi-
tion soft load controller, allowing oper-
ators to easily monitor the switching
devices position and manually test
generator and the system operations.
Switching Devices Status Lights
■ Source 1 Open (Green).
■ Source 1 Closed (Red).
■ Source 1 Trip (Amber).
■ Source 2 Open (Green).

■ Source 2 Trip (Amber).
Front Panel Control Switches and Lights
The combination of the following pilot
devices can be implemented on the unit:
■ AUTO/TEST Switch.
■ SYSTEM TEST Switch.
■ TEST MODE Switch.
■ ALARM SILENCE Switch.
■ READY FOR OPERATION Lamp (White)
— verifies the ATC-5000 status.
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 combi-
nations 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 (2) 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.
