How To Choose A Surge Protector? Pay Attention To These Points!

Many people may not be familiar with surge protectors. Surge protectors are used to protect electrical appliances from damage caused by sudden voltage surges; they are also called lightning arresters and are an important component of lightning protection systems. So, how do you choose the right surge protective device for your needs? Below is a brief introduction on how to select a surge protector.

How to Choose a Surge Protector? Surge protectors are divided into two types based on their application. One type is used to protect the power supply, called a power surge protector, and the other is used to protect low-voltage equipment, called a signal surge protector.

I. Power Surge Protectors

Power surge protectors are mainly used at power supply locations. According to relevant national regulations, power surge protectors are divided into four protection levels. However, in actual use, users typically choose surge protectors of level three or higher based on their budget and the importance of protection, thus maximizing the safety of their electrical equipment.

II. Signal Surge Protectors

Signal surge protectors primarily protect not power supplies, but commonly used low-voltage devices such as computers and televisions. These devices have very poor interference immunity regarding their low-voltage signals. They are mainly installed on various low-voltage signal lines to ensure the normal operation of these devices to the greatest extent possible during lightning strikes.

How to Choose a Surge Protector? In summary, with societal development, people's awareness of protection is increasing. Therefore, we need to select the appropriate surge protection device model based on different scenarios and the equipment being protected. For high-voltage lightning protection, we should choose power surge protectors, while for lightning protection of low-voltage signals from various electronic devices, we should choose signal surge protectors.
