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.
