Type 2 arresters are suitable for installation at the system origin, in intermediate switchboards and near terminal equipment and protect against indirect lightning strikes.

 

SPD Type 2 surge protective devices protect low-voltage consumer systems against overvoltages because they are tested as SPD Type 2 according to IEC 61643-11. The devices are compatible with the System pro M compact series. SPDs with "TS" are optionally equipped with an auxiliary contact.


 

The surge arrester is a device that can be mounted inside the electrical panel, thus upstream of the house installation. Its use makes it possible to put the electrical system on which it is installed into protection.

 

 

The surge arrester will protect the entire system from surges, surges and spikes of electricity that may come from the power line operator, or from atmospheric phenomena such as lightning. These power anomalies can cause serious damage to devices connected to outlets.

 

A surge of electricity can cause the hardware of a pc to break, or short circuit the boards of smartphones, tablets, and home appliances. In the event that the flow of energy suddenly increases dramatically, human life may even be in danger due to electrocution.

 

To prevent this from happening, it is therefore advisable to install a surge arrester.



 

Surge arrestersare divided into three classes:

In class 1 we find devices to be used in areas where adverse weather phenomena such as thunderstorms and lightning usually insist (for example, in mountains). In this case the arrester is mounted in the electrical panel and can withstand several surges without being damaged. Discharge occurs in 350 microseconds, so that excess energy does not reach the system.


In class 2 are surge arresters that protect the system from surges and spikes that may be caused by maintenance work on the line by the operator.

 

In class 3, on the other hand, we find those devices that offer even greater protection: in this case, the surge arrester is installed directly at the electrical outlets in the home.
