Surge Protection Device (SPD)

Description

Surge Protection Device (SPD) – Advanced Protection Against Voltage Surges

A Surge Protection Device (SPD) is a critical safety component designed to protect electrical and electronic equipment from transient overvoltages caused by lightning strikes, grid switching, or electrical faults. SPDs safeguard systems by diverting excess voltage safely to earth, ensuring uninterrupted and reliable operation.

What is a Surge Protection Device?

A Surge Protection Device monitors the electrical line and instantly limits voltage spikes by clamping and diverting surge energy away from sensitive equipment. It plays a vital role in AC and DC systems, especially in solar power installations where outdoor exposure increases surge risk.
