Color-coded connectors like KL-400LFO allow crews to visually verify correct phase wiring at a glance, which is especially valuable during fast-paced load-ins and load-outs.\"}}, {\"@type\": \"Question\", \"name\": \"What safety standards apply to KL-400LFO?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"KL-400LFO meets UL 1691 ( Cam-Type, Locking-Type Separable Connectors), is UL \/ UL \/ cUL Listed under E332947, rated UL Enclosure Types 3R for weather resistance, carries a HB \/ UL94 flame class, and complies with RoHS hazardous substance restrictions. These certifications collectively ensure the connector is safe for professional use in entertainment and industrial environments.\"}}, {\"@type\": \"Question\", \"name\": \"Where is KL-400LFO commonly deployed?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"You will find KL-400LFO at work in portable power distribution for emergency and disaster-response operations. The orange color coding and 400-amp capacity make it particularly well suited for multi-phase power distribution in professional settings.\"}}]}\u003c\/script\u003e\u003c!-- ====== END FAQ + JSON SCHEMA BLOCK: KL-400LFO --\u003e\u003c!-- ==================== DOWNLOAD SECTION ==================== --\u003e\u003cstyle\u003e.kupo-download-section { margin: 2rem 0 0 0; padding: 0; border: 0; background: transparent; box-sizing: border-box;}.kupo-download-section h2 { margin: 0 0 1rem 0; font-size: 22px !important; font-weight: 700; line-height: 1.4; color: #2C3E50 !important;}.kupo-download-link { display: inline-flex; align-items: center; gap: 0.4rem; font-size: 16px !important; line-height: 1.5; color: #111111 !important; font-weight: 600; text-decoration: underline;}\u003c\/style\u003e\u003csection class=\"kupo-download-section\" data-product-id=\"KL-400LFO\"\u003e \u003ch2\u003eDownload\u003c\/h2\u003e \u003ca class=\"kupo-download-link\" href=\"https:\/\/pub-87314d729f334121b80f91e16c4e7f60.r2.dev\/KL-400LFO%20Data%20Sheet.pdf\" target=\"_blank\" rel=\"noopener\" download\u003e  Download KL-400LFO Spec Sheet (PDF) \u003c\/a\u003e\u003c\/section\u003e","brand":"KUPO Stage","offers":[{"title":"K-Lok \/ 400A \/ Inline Female","offer_id":53907598770475,"sku":"KL-400LFO","price":0.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0999\/6887\/6843\/files\/KL-400LFO_b.jpg?v=1782111969","url":"https:\/\/kupostage.com\/products\/kl-400lfo","provider":"KUPO Stage","version":"1.0","type":"link"}
