Surge Protection Device SPD module Metal Oxide Varistors MOV img2

The market has many low-quality surge protectors. LSP uses top MOVs and GDTs, ensuring stable performance and protection after 10 strikes at In: 20kA.

Conventional varistors' design causes uneven heat distribution, leading to failures. LSP's flat tripping device with customized contacts ensures even heat distribution and durable performance without failures.

Surge Protection Device SPD module Metal Oxide Varistors MOV img1

Traditional surge protectors have insufficient disconnection distance and filament formation, risking fires. LSP's flat disconnection device forms an independent chamber, isolating and extinguishing arcs, preventing fires, and ensuring complete isolation of electrodes.
