Lightning Surge Protection For Your
We provide total lightning strike protection solution to all type of buildings:
- Terrace House
- Commercial lot
- Small Medium Size Factory
Surge Protection Device
The Surge Protection Device (SPD) 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 overvoltage
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.

Different Type of
1: Where the building are fitted with
lightning conductor. The Type 1 SPD is recommended in the specific
case of service-sector and industrial buildings, protected by a lightning protection system or a meshed
cage. It protects electrical installations against direct lightning
strokes. It can discharge the back-current from lightning spreading from the earth conductor to the network
conductors.Type 1 SPD is characterized by a 10/350 µs current wave.
2: Installed at distribution board
(DB) within a building. The first gate to prevent lightning strike from entering your house via electricity
supply line. The Type 2 SPD is the main protection system for all low voltage electrical installations.
Installed in each electrical switchboard, it prevents the spread of overvoltages in the electrical
installations and protects the loads. Type 2 SPD is characterized by an 8/20 µs current
SPDs type 3: These SPDs have a low discharge capacity. They must therefore mandatorily be installed as a
supplement to Type 2 SPD and in the vicinity of sensitive loads.Type 3 SPD is characterized by a
combination of voltage waves (1.2/50 μs) and current waves (8/20 μs).
SPDs for CCTV or video
signals: For the protection of CCTV console and
connected display monitor against transient current surge conducted via CCTV and video
- SPDs for telephone lines: For the protection of
receiver against transient current surge conducted via telephone lines.
- SPDs for CATV, TV antenna : For the protection of receiver,
decoder, TV, against transient current surge conducted via CATV, aerial,
SPDs for RS422/485/RS232:
For the protection of instruments connected via RS232/422/485 signal against transient current
surge. Protect your expensive equipments and instruments within your premises. Mounted on
DIN rail and easily retrofitted into your instrument control panel.
