Overview
The Xingleiao 20-40K three-phase power lightning protection box adopts a metal shell design, which is easy to install and maintain. Multiple discharge components such as MOV and GDT are combined to form a multi-stage discharge circuit with low residual voltage, large current capacity, fast response time, small leakage current and change rate, and automatic tripping function for overcurrent and overheating.
Product Details
Xingleiao20-40K three-phase power lightning protection boxAdopting a metal shell design, it is easy to install and maintain. Multiple discharge components such as MOV and GDT are combined to form a multi-stage discharge circuit with low residual voltage, large current capacity, fast response time, small leakage current and change rate, and automatic tripping function for overcurrent and overheating. Suitable for the Chinese power grid with large voltage fluctuations, suitable for various power supply systems such as TN, TT, IT, etc. It can be used for surge protection of low-voltage distribution incoming lines in various communication base stations (computer rooms), computer rooms, office buildings, dispatch centers, etc. It can also be used for protection in special places where modular surge protectors are difficult to meet requirements (such as flammable and explosive).
Product Features
◆ Lightning protection failure alarm function
The module has not been fully plugged into the alarm function
◆ Power indicator function
◆ Lightning protection status indication function
◆ LED lightning strike counting display function
