Surge Protection Devices (SPDs) Overview
Surge Protection Devices (SPDs) are electronic components designed to protect electrical and electronic devices from voltage spikes or surges in the power supply. These voltage transients can occur due to lightning strikes, switching operations, or electrical faults, and they can damage sensitive equipment such as computers, telecommunication systems, industrial machinery, and home appliances. SPDs divert excess voltage away from the protected equipment, ensuring safe and reliable operation. Higher-quality SPDs with greater surge handling capacity, faster response times, multiple protection modes (such as L-N, L-G, N-G), and certifications may have a higher price compared to basic models. When purchasing SPDs, focus on key factors such as surge handling capacity, voltage ratings, response time, and the number of outlets or circuits protected. Ensure the SPD meets your equipment's surge protection requirements, has fast response times to divert surges effectively, and is compatible with your electrical system.
