Surge Protection Device Manufacturer

Protect your equipment from voltage surges and lightning transients with certified SPD solutions. This surge protection device lineup supports stable operation in industrial, commercial, and residential applications.

Surge Protection Device Series

Certified products for safe, stable, and efficient power use.

  AC Surge Protection Device

Choose an AC surge protection device for utility-fed systems such as panels, distribution boards, MCCs, and control cabinets.

In residential applications, this typically means installing a “whole house surge protector” — an AC surge protection device mounted at the main service equipment and selected based on the wiring method and panel layout.

If you’re designing layered protection, place a type 1 surge protection device at the service entrance when incoming exposure is highest. Add a type 2 surge protection device at key distribution panels to limit residual surges closer to loads.

  DC Surge Protection Device

Use a DC surge protection device for DC rails and DC-fed equipment such as power supplies, control systems, and DC distribution. It’s a practical choice for sites where DC transients can stress sensitive electronics over time.
