Surge Protection Devices (SPDs) are vital components in safeguarding electrical installations—whether in industrial plants, commercial buildings, or residential properties—from damaging voltage transients caused by lightning strikes, switching operations, or utility grid anomalies. By installing high-quality surge protection device manufacturers’ products, facility managers and system integrators can ensure equipment uptime, extend the lifespan of sensitive electronics, and meet stringent safety standards such as UL 1449 and IEC 61643-11.
