FUNCTIONAL DESCRIPTION
The SPD3200-TN-E is designed to protect three
phase power systems against damage from surges
and spikes caused by lightning and other electrical
sources. The unit is intended for point of entry or
main board protection and is connected in parallel
with the power system via its own safety disconnect
MCB.
Differential and common mode transients are
diverted to mains earth via internally mounted surge
diverters through a common earth bus. All internal
connections are designed for minimum impedance to
enable maximum current flow back to earth.
This model ( SPD3200-TN-E ) is designed for use
in systems with a grounded neutral where
connected for N-E operation. Line transients are
diverted directly in L-E mode.
OPERATION
Indicators - The operation status of the SPD3200 is
indicated by blue indicators on the front panel. These
4 indicators show the status of each of the L and N
surge diverters inside the unit. The indicators are
blue when the unit is powered on and operating.
When any of these extinguishes then the
corresponding internal surge diverter should be
replaced. When any indicator fails the protection
relay contacts change over. The power failure alarm
will also operate when mains voltage falls below
180VAC.
External safety disconnector - The prescribed safety
disconnector is provided as part of the unit and is a
63A MCB specially tested for this application. This
MCB is mounted on the inside of the unit and is
where all connections are made.
Surge counter - The unit comes with a LCD display
surge counter. The counter will operate each time
there is a current pulse event occurring between L-E
and has a threshold trigger level of <1.5kA. Each
event will cause the counter to increment.
Key lock - The unit comes with a key lock on the
front panel to prevent uncontrolled access.
Cable entry – L and N connections are made through
a separate cable gland entry point at the top left of
the unit. Earth connections can be made via a
separate cable gland connection also on the top of
the unit.
