Surge Protective Devices (SPDs) protect electronic equipment and electrical systems from voltage spikes caused by lightning, power surges, or other disturbances. They divert excess voltage to the ground, preventing damage to sensitive devices. SPDs are essential for maintaining electrical infrastructure, improving system reliability, and extending the lifespan of connected equipment.

Voltage protectors safeguard electrical equipment from damage caused by voltage fluctuations, such as surges, spikes, or sags. They monitor voltage levels and intervene when they exceed safe thresholds, either by disconnecting power or diverting excess voltage. This helps prevent malfunctions, degradation, or failure, ensuring reliable operation and longer-lasting equipment.
