Understanding Surge Protective Device Ratings

How to know what kA rating to use.Selecting the appropriate surge protective device (SPD) can seem like a daunting task, especially with all of the different types on the market today.

Rating of Backup Breaker for Surge Protective Device

Quite often, customer will ask, which rating of MCB or RCDs to be chosen to protect the surge protective devices (SPD)?

The Difference Between Lightning Protection And Surge Protection

Lightning and surge protection are two elements of an effective electrical protection system.

Surge Protection: What Should Be Noted?

Effective surge protection is not just simply installed. It has to be individually coordinated – to the system that is to be protected and the ambient conditions that are prevalent on site.

Surge Protector FAQ

Do surge protectors last forever?No, they do not. Each time a surge protector reroutes a power surge away from your connected equipment, the internal structure of the protector takes a little bit of damage.

How to protect your solar power system from lightning

Lightning is a common cause of failures in photovoltaic (PV) and wind-electric systems. A damaging surge can occur from lightning that strikes a long distance from the system, or even between clouds. But most lightning damage is preventable.
