|Surge Protection Device (SPD):
The Surge Protection Device is a component of the electrical installation protection system. This device is connected in
parallel on the power supply circuit of the loads that it has to protect. It can also be used at all levels of the power supply
network. This is the most commonly used and most efficient type of over voltage protection.
|Surge protection Device (SPD) with plug in cartridge ensure
general protection of electric equipment and protection in
common and differential mode for domestic, industrial and
commercial buildings. SPDs protect electric and electronic
equipment against transients, originating from lightning and
switching transient sources. For a residential building, SPD
serves as "1st line of defence" when it is installed at the
main incoming power distribution board (DB).
The SPD is designed to be easily installed in power and
control panels using standard DIN-rail mounting brackets.
This series of product offers 20,000 - 100,000 amps of both
normal and common mode surge protection. The SPD is
available in single phase, split phase, three phase (3 wires)
and three phase (4 wires) configurations. Replaceable
modules allow for easy maintenance and mount directly into
the SPD base assembly, simplifying the replacement
process. The status of the surge protector modules can be
monitored through the indicator lenses or remotely through
the alarm terminals (optional features). Available as option,
the replacement cartridge allows simple replacement without
the need to cut-off the power supply, Cartridges are
available for all discharge
|currents (80kA, 60kA, 40kA, 20kA) with indicator. SPD effectively reduce the interference coupling that can occur from
transient surge voltages, even significantly below the limits prescribed by insulation co-ordination according to EN 60664-3
/ DIN VDE 0110-3. This means that the entire system is exposed to less malfunction. We offer different products for
different mains types and voltage levels. Even for photovoltaic (Solar energy systems) applications, there is a special
protection according to EN 50539-11/ VDE 0675-39-11: 2010 available.
