Transient surges, characterized by sudden voltage peaks, pose a significant threat to electrical installations. These surges, often originating from load switching or lightning strikes, can lead to catastrophic equipment failure, operational disruptions, and costly repairs. Surge protective devices, such as those offered by ABB, provide a critical layer of protection by diverting excess voltage and safeguarding sensitive equipment. Proper surge protection is essential for maintaining operational continuity and minimizing financial losses.
