device (SPD) is an electrical safety component designed to limit transient overvoltages and redirect excessive current safely to ground.<\/p>\n\n\n\n<p>These voltage spikes can originate from:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Lightning strikes<\/li>\n\n\n\n<li>Utility grid switching<\/li>\n\n\n\n<li>Motor startups and shutdowns<\/li>\n\n\n\n<li>Generator switching<\/li>\n\n\n\n<li>Internal electrical faults<\/li>\n\n\n\n<li>Industrial equipment operation<\/li>\n<\/ul>\n\n\n\n<p>When a surge occurs, the SPD reacts within nanoseconds, diverting excess energy away from connected equipment.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\"

Excess Voltage<\/strong><\/h3>\n\n\n\n<p>Under normal operating conditions, an SPD remains inactive.<\/p>\n\n\n\n<p>When voltage exceeds a predetermined threshold, the device activates instantly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-diverting-surge-energy\"><strong>Diverting Surge Energy<\/strong><\/h3>\n\n\n\n<p>The surge current is safely redirected to the grounding system rather than passing through connected equipment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-returning-to-normal-operation\"><strong>Returning to Normal Operation<\/strong><\/h3>\n\n\n\n<p>After the surge event ends, the SPD automatically returns to standby mode.<\/p>\n\n\n\n<p>This process helps protect:<\/p>\n\n\n\n<ul
