What Is a Surge Protective Device (SPD)? Complete Guide for Beginners
TABLE OF CONTENT In modern homes, commercial buildings, and industrial facilities, sensitive electronics and control systems are constantly exposed to short, high‑energy spikes in voltage known as surges. A surge protective device (SPD) is a dedicated protective component that limits these transient overvoltages and diverts the associated surge current away from equipment and safely to […]
