Product Description

I. Overview


EPP series AC power supply lightning protector consists of several monolithic lightning protection chips, which can be freely combined into single-phase or three-phase protection for different power distribution systems to prevent damage to low-voltage power equipment from inductive overvoltage or operational overvoltage. epp80t is usually used for secondary protection.

Site conditions before installation

1,There is a reliable grounding system, and the grounding resistance of the distribution cabinet's grounding pile (strip) is measured (SPD installation), and its resistance should meet the national standard.

2,Space should be left in the distribution cabinet for SPD installation.

Note: L is the fire wire, N is the zero wire, E is the ground wire.


Precautions after installation

1,Check if the air switch is turned off and carry out to make sure the SPD is in working condition.

2,Do not install in thunderstorm.



This product is installed in parallel in the line, and its operation should be checked regularly, especially after thunderstorms. The inspection is divided into appearance inspection and performance test.

Appearance inspection. Each lightning protection module has deterioration indication. When working normally: the indicator is green; after aging: the indicator goes out. the SPD should be replaced in time after aging.

Performance testing. According to the national lightning protection code, test at least once a year, and measure V1mA and IL≤20μA of L-PE and N-PE respectively with lightning protection element tester as qualified.
