Surge protection devices (SPDs) safeguard valuable and sensitive equipment in electrical systems, such as network devices, automated machinery, precision instruments, communications gear, and military equipment. SPDs protect integrated circuits (ICs) and software components from high-voltage surges typically caused by lightning strikes, line faults, or switching operations.

Why Surge Protection is Essential

During a lightning strike, the massive electric current can directly damage overhead power lines, tall structures, and other equipment it contacts directly. In addition, the high voltages and currents from a lightning strike induce damaging voltage spikes in connected low-voltage electrical systems. This can destroy sensitive electronics and harm people indoors. Installing appropriate low-voltage surge protection devices (SPDs) defends vulnerable equipment and residential power entry points.

Our Surge Protection Portfolio

Among our complete lineup of surge protection devices, there are two significant SPD categories. The first type is UL certified (compliant with American and Canadian standards) and is used to protect low-voltage distribution systems and connected equipment. Another important type is specifically engineered to protect DC systems used in solar power generation equipment. Both types of Surge Protection Devices come in modular configurations (modules easily plugged into bases), designed for convenient operation.

Additionally, specialized Surge Protection Devices capable of dissipating large currents (with a maximum discharge current of over 80 kA) are available. These devices adopt a single-pole (single-phase), "integrally molded" design (cast in self-extinguishing resin) to enhance insulation and mechanical strength.
