With its 3+1 configuration, it provides enhanced protection for phase-to-neutral and neutral-to-earth paths. This <strong>240V\u30b5\u30fc\u30b8\u4fdd\u8b77\u88c5\u7f6e<\/strong> is tested according to IEC\/EN 61643-11 and withstands lightning currents up to Iimp 25 kA per pole (10\/350 \u03bcs). It is ideal for service entrance installations where reliable first-stage protection is required.<\/section>\n<section id=\"features\">\n<h3>\u4e3b\u306a\u7279\u5fb4<\/h3>\n<ul>\n<li>IEC\/EN
