• Compact solution for primary protection
• DIN43880 base, 35 mm DIN-rail mountable
• Thermally protected
• Includes dry-contact alarm
Applications
• Any SWB remote from system M.E.N.
• For use with any 275-300V L-N SPD
• Ideal companion to Eaton SPDV60-300
• Pumps or other remotely-located plant
DO NOT CONNECT TO LIVE OR ACTIVE LINES!
FUNCTIONAL DESCRIPTION
The SPDT60-255 is designed to provide protection
between Neutral and Earth circuits where Line-
Neutral protection is installed remote from the M.E.N.
link. Under normal conditions, the coupler does not
conduct, preventing earth loops and inter-circuit
coupling. Under surge conditions, the Line-Neutral
SPD(s) will conduct surge currents to Neutral,
resulting in a high Neutral voltage. At this point, the
SPDT60-255 conducts, effectively interconnecting
the circuits for the duration of the surge and shunting
the high Neutral voltage to Earth. The unit is intended
for point-of-entry or sub-board protection and may be
directly connected without fuses. The unit features a
plug-in module that may be replaced without rewiring
in the event of a fault. Check that the model you have
purchased is rated correctly for your power system.
.
This model (SPDT60-255) is designed for Neutral-
to-Earth connection only in single and 3-phase
power systems, with a grounded neutral, in the
range of 220-250V(380-440V). UNDER NO
CIRCUMSTANCES MUST THIS DEVICE BE
CONNECTED TO A LIVE OR ACTIVE LINE.
OPERATION
The operational status of the unit is shown by a flag
indicator on the front of the module. In normal
operation, the flag is green. If the unit is damaged,
the flag changes to red, indicating that replacement is
necessary. A ‘dry-contact’ alarm output is fitted to the
base unit and will change over if the module is faulty
or not in place.
WARRANTY
Eaton Power Quality warrants this unit against faulty
parts and workmanship for a period of 12 months
from the date of purchase. If this product fails to
operate correctly, please contact your Eaton
representative. This warranty doesn’t cover neglect
or intentional misuse. As this product is intended for
use in electrically harsh environments no claim is
made of suitability for purpose. This unit is designed
to reduce the likelihood of damage, not prevent it.
Please also note that an excessive surge, such as
from a direct lightning strike to the site or a power
system fault, may cause damage to the unit and
render it inoperable. A unit that has been damaged in
this way is not warrantable.

INSTALLATION
Refer to the procedure and diagram shown to
connect the SPDT60-255.
PROCEDURE:
1. CHECK
• Always work safely – disconnect power
before making connections.
• All wiring must be carried out by suitably
qualified personnel according to the
applicable standards.
• Check for correct operating voltage and
power system. This model (SPDT60-255) is
designed for power systems in the range of
220-250V(380-440V). If your power system
is “delta” (i.e. ungrounded), or a different
voltage, this model is not suitable.Please
contact your supplier.
• Connect only between Neutral and Earth.
• No fuse is necessary.
2. INSTALL
• Locate a suitable position for the SPD,
ensuring adequate space for cables. Do not
install above heat-generating objects or in
any position that is exposed to weather.
• Plan for cables as short as possible.
• Install unit to DIN-rail in switchboard or
cabinet.
3. CONNECT
• Connect wiring - refer to connection
diagrams. If using stranded cable, always
use wire ferrules for lowest resistance and to
prevent damage to the wire.
• If connecting with Eaton SPDV60 SPDs, use
supplied neutral linking bar.
• Use a suitably-rated cable for power
connections. Cable should be rated for
operation at the system voltage and should
be 6mm2to 25mm2.
• Use short cables for all connections or
protection will be reduced.
• Use a suitably-rated cable for alarm
connections. Cable should be rated for
operation at the system voltage and should
be 0.5mm2to 1.5mm2.
4. NOTES:
• Maximum alarm relay resistive load is 2A.
• Unplug the alarm connector for termination.
• It is recommended not to connect the alarm
contacts to AC mains circuits if possible, to
prevent flashover from surges on the AC line.
Connect to a PLC or BMS if available.
• Do not Megger test cabling with unit
connected.
EARTHING
For proper operation, all surge diverters rely upon a
good earth connection:
• The main earth wire (from earth link on
switchboard to ground rod or system) MUST be
as short and direct as possible. Extra cable must
not be looped.
• Earth connections from the unit to neutral or earth
link MUST be as short as possible.
Failure to consider the above points can result in
improper operation of the unit and possible
damage to the installation.
