What is the difference between a 1000v dc spd t1+t2 and a type 2 only SPD?<\/h3>\n<p>The KY-15T\/G1000 combines Type 1 lightning current capability with Type 2 low residual voltage protection,<br \/>\nwhile Type 2 alone cannot handle direct lightning currents.<\/p>\n<h3>Q2. Can the 1000v dc spd t1+t2 be used in residential PV combiner boxes?<\/h3>\n<p>Yes, it is suitable for residential and commercial PV combiner boxes operating at 1000V DC.<\/p>\n<h3>Q3. Does KY-15T\/G1000 include remote alarm contacts?<\/h3>\n<p>Yes, alarm terminals (NO\/NC) are reserved and rated 220V, 0.5A as specified in the datasheet.<\/p>\n<h3>Q4. Which standards does the KY-15T\/G1000 comply with?<\/h3>\n<p>IEC 61643-31, GB\/T 18802.31, CE, UKCA, and RoHS certifications are covered.<\/p>\n<\/section>\n<p><!-- ========================= JSON-LD: FAQ ONLY ========================= --><br \/>\n<script type=\"application\/ld+json\">\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"FAQPage\",\n  \"mainEntity\": [\n    {\n      \"@type\": \"Question\",\n      \"name\": \"What is the difference between a 1000v dc spd t1+t2 and a type 2 only SPD?\",\n      \"acceptedAnswer\": {\n        \"@type\": \"Answer\",\n        \"text\": \"The KY-15T\/G1000 combines Type 1 lightning current capability with Type 2 low residual voltage protection, making it suitable for main PV protection points.\"\n      }\n    },\n    {\n      \"@type\": \"Question\",\n      \"name\": \"Can the 1000v dc spd t1+t2 be used in residential PV combiner boxes?\",\n      \"acceptedAnswer\": {\n        \"@type\": \"Answer\",\n        \"text\": \"Yes, it is designed for residential and commercial PV combiner boxes operating at 1000V DC.\"\n      }\n    },\n    {\n      \"@type\": \"Question\",\n      \"name\": \"Does KY-15T\/G1000 include remote alarm contacts?\",\n      \"acceptedAnswer\": {\n        \"@type\": \"Answer\",\n        \"text\": \"Yes, alarm terminals (NO\/NC) are reserved and rated 220V, 0.5A as specified in the datasheet.\"\n      }\n    },\n    {\n      \"@type\": \"Question\",\n      \"name\": \"Which standards does the KY-15T\/G1000 comply with?\",\n      \"acceptedAnswer\": {\n        \"@type\": \"Answer\",\n        \"text\": \"IEC 61643-31, GB\/T 18802.31, CE, UKCA, and RoHS certifications are covered.\"\n      }\n    }\n  ]\n}\n<\/script><\/p>\n<section id=\"cta\"><a class=\"btn\" href=\"\/contact-us\">Request a Quote for 1000v dc spd t1+t2<\/a><\/section>\n","protected":false},"excerpt":{"rendered":"<p>(1) The <strong data-start=\"276\" data-end=\"298\">1000v dc spd t1+t2<\/strong> KY-15T\/G1000 provides combined Type 1+2 surge protection for photovoltaic systems.<\/p>\n<p><br data-start=\"381\" data-end=\"384\" \/>(2) Designed for PV combiner boxes, inverters, and DC feeders, compliant with IEC 61643-31 and CE\/UKCA\/RoHS standards.<\/p>\n<p><br data-start=\"502\" data-end=\"505\" \/>(3) Includes remote alarm contact option, replaceable module design, and shared wiring\/dimension diagrams for T1+T2 series.<\/p>","protected":false},"featured_media":1534,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[26],"product_tag":[],"class_list":{"0":"post-968","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-dc-spd","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/cnkuangya.com\/ar\/wp-json\/wp\/v2\/product\/968","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cnkuangya.com\/ar\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/cnkuangya.com\/ar\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/cnkuangya.com\/ar\/wp-json\/wp\/v2\/comments?post=968"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/cnkuangya.com\/ar\/wp-json\/wp\/v2\/media\/1534"}],"wp:attachment":[{"href":"https:\/\/cnkuangya.com\/ar\/wp-json\/wp\/v2\/media?parent=968"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/cnkuangya.com\/ar\/wp-json\/wp\/v2\/product_brand?post=968"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/cnkuangya.com\/ar\/wp-json\/wp\/v2\/product_cat?post=968"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/cnkuangya.com\/ar\/wp-json\/wp\/v2\/product_tag?post=968"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
