Lightning Surge Protection Installation for whole house


Surge Protection Device (SPD):

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 protection.

Lightning Surge Protection DeviceSurge 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 SPDs

SPDs type 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.

SPDs type 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 wave.  

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).
