Do you understand the
importance of a
Surge
Protection Device - SPD?
What is a SPD?
The acronym SPD stands for Surge Protection Devices.
These are devices that can detect transient voltages in the electrical network, diverting surge currents so that electrical and electronic devices are not affected by power surges.
Essential products to ensure the proper functioning of electronic devices.
What are SPD classes?
According to NBR IEC 61643-1, SPD can be classified into three classes: class I, II and III.
SPD Class I
It is intended for protection against conducted electrical surges, resulting from direct atmospheric discharges, generally recommended for places with high exposure and/or that are equipped with SPDA - Atmospheric Discharge Protection System.
SPD Class II
It is intended for protection against electrical surges caused by indirect atmospheric discharges, that is, they fall close to the building or the power or data transmission lines.
SPD Class III
It is a protective device that must be used in close proximity to protected equipment. Usually used as a protective complement or in places with low exposure.
What are the benefits of having a SPD?
There are several benefits for you and your equipment:
Protection against lightning and electrical surges
Extend the life of your electronics
Ensure equipment functionality
Financial savings, since it reduces the recurrence of product exchange and maintenance of defects.

Where do
electrical surges come from?
Most people think that electronics will only burn from a lightning strike, but actually lightning is just one of the factors and it's not the biggest one.
The main causes of
electrical
surges are:
80%
Start of electric motors, it can be an industry near your house, elevators, washing machine, etc.
15%
Atmospheric discharges, the famous rays.
5%
Switching in the electrical network with the maintenance of the energy concessionaire itself.
