Engineered for commercial and industrial electrical systems, THOR's heavy-duty power surge protectors (also industry-known as TVSS or AC SPDs) play a vital role in preventing transient overvoltages caused by lightning strikes, switching operations, or grid fluctuations.
As a trusted manufacturer since 2006, our surge protectors divert surge current safely to the ground, clamping the voltage within a secure range. Fully compliant with IEC standards, our AC SPDs are widely used to safeguard PLCs, variable frequency drives (VFDs), power panels, and data centers from insulation breakdown and catastrophic equipment failure.
Applications of Industrial Power Surge Protectors (TVSS)
-
Main Distribution Boards (MDB): Heavy-duty AC SPDs designed to handle direct lightning currents at the facility entrance.
-
Sub-Panels & Motor Control Centers: Reliable power surge protectors to mitigate internal switching transients and protect VFDs.
-
Data Centers & IT Infrastructure: Low clamping voltage TVSS solutions to prevent data loss in mission-critical servers.
