Tr a n s f er Switches
Standard and Optional Features
Customer Inputs
26D. Go to Emergency (Source 2)
Provides the capability for an
external contact closure to
initiate a transfer to the
Source 2 power source.
This includes starting the
generator, performing the
programmed time delays
and the transfer operation.
Retransfer will occur when
the external contact is
opened. This is a fail-
safe function.
36. Load Shed From Emergency
Provides the capability for an
external NC contact to initiate
a load circuit disconnection
from the Source 2 power
source. If the load circuit is
connected to Source 2 and
the contact is opened, then
a retransfer to Source 1 is
completed if Source 1 is
available. If Source 1 is not
available, then the transfer
switch will transfer to neutral.
If the load circuit is connected
to Source 1 and the contact
is open, then a transfer
Source 2 is prohibited.
16. Integral Overcurrent
Protection
Provides thermal-magnetic
overcurrent protection
integral to the power
switching device(s). All
Feature 16 options include
a “Lockout” function. If the
power switching breaker trips
on
an overcurrent condition,
then “Lockout”
is displayed
on the automatic transfer
controller display and
automatic operation is
prevented until the
appropriate source is
manually reset. On non-
automatic switches, a blue
light is supplied to indicate
the “lockout.”
16B. Integral Overcurrent
Protection on Both Power
Source Switching Devices
Provides integral overcurrent
protection on both Source 1
and Source 2 power
switching devices.
16E. Integral Overcurrent
Protection on the Source 2
Power Switching Device
Provides integral overcurrent
protection on the Source 2
power switching device.
16N. Integral Overcurrent
Protection on the Source 1
Power Switching Device
Provides integral overcurrent
protection on the Source 1
power switching device.
16S. External Overcurrent
Protection on the Source 1
Power Switching Device
Provides overcurrent
protection on the Source 1
power switching device.
18. Metering
The ATS controller provides
voltage and frequency
readings. If additional
metering functions are
required, Eaton offers a
series of digital meters that
may be added to the ATS.
The meter type can provide
simple current and voltage
readings or more capable
meters providing Power,
Demand and energy
readings.
Available with an optional
communications interface.
(See Feature 48—
Communications for available
communication modules.)
Feature 18 metering options
include all required external
devices (CTs, etc.) for a fully
functioning metering system.
IQ 130/140/150
IQ 130
This digital meter provides
basic current and voltage per
phase (L-L, L-N) and min./
max. readings (I, V). Optional
communication RS-485,
Modbus RTU.
IQ 140
In addition to basic current
and voltage, will provide
frequency, power
measurements real, reactive
and apparent power, total (W,
VAR, VA). Optional
communication RS-485,
Modbus RTU.
IQ 150
In addition to basic current/
voltage/frequency and power
readings, will provide Energy
Real reactive and apparent
(Wh, VAR, Vah). Optional
communication RS-485,
Modbus RTU.
IQ 250/260
IQ 250
This digital meter provides
current per phase and current
demand, voltage (L-L, L-N)
and frequency. Power,
energy and demand readings.
Real, reactive and apparent
power and energy, power
factor. RS-485
communications, Modbus
RTU or ASCII. Optional I/O
slots available.
IQ 260
In addition to all of the
features of the IQ 250, power
quality analysis is available
with THD voltage and current
per phase.
Power Xpert 2000
Provides either a Power Xpert
PXM 2250, PXM 2260 or
PXM 2270 meter.
Power Xpert 4000, 6000, 8000
Provides one of the Power
Xpert meters with or without
graphic displays.
18W. Ammeter Side Metering
Provides an ammeter
for monitoring the load
side circuit.
20A. Rear Bus Provisions
Provides Source 1, Source 2
and Load Circuit rear
accessible bus stabs
with provision for bus bar
connection. Eaton transfer
switches are provided
with either front or rear
(dependant on switch type)
connected solderless screw-
type terminals for power
cable connection as standard.
21A. Optional Power Cable
Connection Terminals
Eaton transfer switches are
provided as standard with
Source 1, Source 2 and load
circuit solderless screw-type
terminals for power cable
connection. Alternate
terminal wire sizes, and
compression lug provisions
may be available dependant
on transfer switch type and
ampere rating.
32. Delayed Transition Transfer
Modes for Open Transition
Transfer Switches
Provides delayed transition
transfer modes for an open
transition transfer switch.
Often used in systems with
inductive loads, a delayed
transition transfer switch
may prevent or reduce inrush
currents due to out-of-phase
switching of inductive loads.
