Surge Protection Solutions for Every Application

Thor SPDs are engineered for demanding environments across commercial buildings, industrial facilities, PV systems, and telecommunications infrastructure. Explore our application-specific solutions — each backed by IEC 61643 compliance, proven field performance, and flexible OEM customization.

Low-Voltage Power System

Low-Voltage Power System

The stability of any facility starts with its power supply. Lightning strikes and grid switching events can send destructive surges through power lines, damaging critical infrastructure and causing downtime. Thor’s comprehensive range of AC surge protective devices with high KA and low Up rating provides solid defense for main panel, power distribution systems within low-voltage systems, making sure the power supply stays protected and operates with consistent stability.

Photovoltaic (PV) & Renewable Energy

Since solar systems are installed outdoors and span large surfaces, facing a greater likelihood of being struck by lightning. Thor delivers specialized protection for the unique requirements of DC photovoltaic systems. Our high-performance SPDs protect solar combiner boxes, inverters, and battery energy storage systems (BESS) against high-voltage transients even in harsh conditions, securing your return on investment in green energy.

Telecommunications & 5G

Telecom towers and network infrastructure are highly exposed, making lightning vulnerability a critical concern. Thor supports global 5G expansion with industrial-grade protection, featuring 48V DC SPDs and Antenna surge protectors that keep networks secure. Our devices handle high discharge currents with low residual voltage for stable connectivity even during severe storms.

Data Centers & Server Rooms

In a data-driven world, downtime is not an option. Data centers house millions of dollars in sensitive server equipment that is highly vulnerable to even minor electrical surges. Thor provides mission-critical surge protection designed to protect Power Distribution Units (PDUs) and server racks. Our solutions secure ‘five nines’ reliability, protecting your digital assets from data corruption and hardware failure.

Intelligent Security & PoE Networks

Security cameras and monitoring systems are the eyes of modern safety, but long outdoor cable runs act as antennas for induced lightning surges. Thor specializes in protecting sensitive low-voltage networks. Our Power-over-Ethernet (PoE), signal and coaxial SPDs prevent destructive transients from traveling through network cables (Cat5/Cat6) to destroy expensive cameras, NVRs, and network switches.
