Surge protectors are essential devices designed to safeguard electrical equipment from voltage spikes and transient surges. They are widely used in industrial, commercial, and residential settings to protect sensitive electronics, automation systems, and machinery. Key features include high surge absorption capacity, fast response time, and durable construction. Common products in this category include plug-in surge protectors, panel-mounted surge suppressors, DIN rail surge modules, and SPDs (Surge Protective Devices) for power distribution systems. These devices ensure reliable operation and longevity of connected equipment by diverting excess voltage away from critical components.
