A surge protection device (SPD) is designed to protect electrical systems and equipment from sudden voltage spikes. These spikes can occur due to lightning strikes, power outages, or switching operations in the electrical grid. Understanding what is surge protection device helps homeowners and businesses prevent costly damage and ensure long-term system reliability.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-a-surge-protection-device-spd\"><strong>What Is a Surge Protection Device (SPD)<\/strong><\/h2>\n\n\n\n<p>A surge protection device is an electrical component that limits excessive voltage by diverting or grounding surge currents.
