Use a 3P breaker (like the HLF390S) for three-phase loads; single-phase circuits only need a 1P or 2P device.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIs this MCB compatible with other Hager distribution boards?\u003c\/strong\u003e\u003cbr\u003eYes. The HLF390S is a standard DIN rail MCB and mounts directly onto Hager consumer units and panel boards alongside other Hager modular devices (RCCBs, RCBOs, isolators) on the same busbar system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCan I install this myself?\u003c\/strong\u003e\u003cbr\u003eNo. MCBs are installed inside a distribution board and connected to live supply conductors — this must be done by a licensed electrician in accordance with local wiring regulations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Hager","offers":[{"title":"Default Title","offer_id":41797539102819,"sku":"HLF390S","price":438.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0570\/6570\/1475\/files\/HLF390S.webp?v=1786954811","url":"https:\/\/www.deluxeuae.com\/products\/hager-100a-3p-mcb-10ka-hlf390s","provider":"Deluxe Electricals","version":"1.0","type":"link"}
