What is a Surge Protection Device (SPD)?

A Surge Protection Device (SPD) is an electrical safety device that protects electrical installations and electronic equipment from voltage spikes caused by lightning, switching operations, utility disturbances, and transient surges. SPDs divert excess surge energy safely to the grounding system, preventing damage to valuable equipment and minimizing operational downtime.

Modern electrical installations—including industrial plants, data centres, hospitals, telecom networks, solar power plants, commercial buildings, and residential properties—depend on SPDs to ensure reliable electrical protection and uninterrupted system performance.
