The Difference Between A Primary Surge Protector And A Secondary Surge Protector

First, we know that surge protective device are also called lightning arresters. They are divided into power surge protector and signal surge protectors based on the type of equipment they protect. Power surge protectors are further divided into four levels: Level 1, Level 2, Level 3, and Level 4. So what are the differences between them? Below, Yizao Lightning Protection Technology will give you a brief introduction.

I. Different Protection Ranges

Level 1 surge protectors have a higher discharge current than Level 2 surge protectors. The protection level of Level 1 is also higher than that of Level 2.

II. Different Functions

Level 1 surge protectors, due to their larger protection range, primarily function to discharge current. This protects the normal operation of the power supply. Level 2 surge protectors, on the other hand, limit excessive voltage and prevent sudden voltage spikes.

III. Different Forms

Level 1 surge protectors are mainly used in power surge protection boxes. Level 2 surge protectors are generally only used as surge protection modules in products.

IV. Different Application Scenarios

Level 1 surge protectors are mainly installed outdoors in large buildings or at the power inlet of large electrical equipment, or inside the main distribution box. Level 2 surge protectors, on the other hand, are primarily used inside distribution boxes within buildings.

This concludes the introduction to the differences between Level 1 and Level 2 surge protectors. In general, the selection of a surge protection device should be based on different needs and specific scenarios.
