ATC-300 2-Position Contactor
Based Transfer Switch
3.5.2 Optional Features
The following is a list of the optional features for the ATC-300
Controlled ATS. All features or combinations of features may not
be available on specific ATSs
9B. Maintenance Selector Switch (MSS)
Marked “OFF”, “ON”. This feature provides selector
switch disconnection of control to transfer thus allowing
testing of the transfer switch control logic circuitry with-
out initiating load transfer. Positioning the MSS in the
“OFF” position isolates the control circuit, permitting man-
ual operation of the transfer switch or testing of logic cir-
cuitry without load transfer.
14. Relay Auxiliary Contacts : This feature provides form “C”
relay auxiliary contacts.
14C. Source 1 Present : Provides four (4) normally open and four
(4) normally closed contacts. The relay is energized when
Source 1 is available.
14D. Source 2 Present : Provides four (4) normally open and four
(4) normally closed contacts. The relay is energized when
Source 2 is available.
15. Switch Position Indication Contact
This feature provides a contact that indicates if the power
switching device is in the “Open” or “Closed position.
15G. Source 1 Position Indication Contact
This feature provides 3 Dry Form “C” contacts that indi-
cate the position of the Source 1 power-switching device.
15H. Source 2 Position Indication Contact
This feature provides 3 Dry Form “C” contacts that indi-
cate the position of the Source 2 power-switching device.
18. Metering
This feature includes all required external devices (CTs,
shorting blocks, fuses, etc.) for a fully functional metering
system.
18O. IQ Analyzer Normal (S1) Only
18P. IQ Analyzer Emergency (S2) Only
18Q. IQ Analyzer Normal (S1) & Emergency (S2) Switch Select-
able
18V. IQ Analyzer Load
18R. IQ DP-4000 Normal (S1) Only
18S. IQ DP-4000 Emergency (S2) Only
18T. IQ DP-4000 Normal (S1) & Emergency (S2) Switch Select-
able
18U. IQ DP-4000 Load
18AN. IQ 250/260 Normal (S1) Only
18AE. IQ 250/260 Emergency (S2) Only
18AL. IQ 250/260 Load
18W. Ammeter
A single ammeter is a true RMS sensing device that dis-
plays single phase current only.
The ammeter can be mounted on Source 1, Source 2, or
load. The meter can also be configured for 1, 2, or 3-phase
sensing by supplying one meter per phase for Source 1,
Source 2, or load. Ammeters for both Source 1 and Source
2 can also be grouped together.
23L. 24 Hour, 7day, 365 Day Programmable Plant Exerciser
This plant exerciser has two channel electronic time
switches with 365-day, 7-day, 24-hour programming. Each
channel can be independently programmed and can provide
up to 400 events. The plant exerciser offers daily, weekly
or annual programming capability with up to 99 separate
holiday periods of any duration and priority. An LCD display
indicates load status, time-of-day, weekday and date.
29G. Auto/Manual Operation
This feature provides 2-position auto/manual selector
switch marked “Auto/Manual” which permits the selection
of automatic or manual operation. Once the selector switch
is transferred to manual mode, manual transfer between
Normal (S1) and Emergency (S2) can be achieved by oper-
ating another 2-position selector switch marked “Normal-
Emergency”.
38. Stainless Steel Logic Cover
38A. Stainless Steel Cover for Device Panel
Provides an added level of security by providing a pad lock-
able stainless steel cover for use with standard transfer
switch device panel. The cover is designed for NEMA 1,
3R, 4X, and 12 applications.
38B. Stainless Steel Cover for Controller
Provides an added level of security by providing a pad lock-
able stainless steel cover for use with standard transfer
switch logic controllers and/or associated device panels.
These covers function with Eaton’s ATC series logic con-
trollers and device panels. The covers are designed for
NEMA 1, 3R, 4X, and 12 applications.
41. Space Heater With Thermostat
This feature provides a space heater and non-adjustable
thermostat. External control power is not required.
41A. Space Heater With Thermostat - 100 Watt
This feature provides a 100 watt (W) space heater with a
non-adjustable thermostat.
49B. Sensing Isolation Transformer (Up to 600 VAC only)
This feature provides 3-phase, 4-wire for Source-1 and
Source-2 sensing input on ATC controller for a high resis-
tance grounded delta system.
