An RCCB\/ELCB like the CF485Z monitors earth leakage current and trips on imbalance, protecting against electric shock and earth faults an MCB cannot detect. The two are complementary and commonly installed together in a distribution board.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat does the 300mA sensitivity rating mean — will it protect against electric shock?\u003c\/strong\u003e\u003cbr\u003eThe CF485Z trips at a 300mA earth-leakage imbalance. This is a fire\/equipment-protection sensitivity — typically used as main incoming or sub-main protection on larger boards — rather than the 30mA rating required for direct personnel shock protection on final circuits, which should use separate 30mA RCCBs\/RCBOs downstream.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHow many poles do I need — what does 4-pole (4P) mean for this circuit?\u003c\/strong\u003e\u003cbr\u003e4-pole means the device switches all four conductors of a three-phase-plus-neutral supply. Use a 4-pole RCCB on three-phase boards or where neutral isolation is required; single-phase circuits typically use a 2-pole device instead.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCan I install this myself?\u003c\/strong\u003e\u003cbr\u003eNo. The CF485Z is a distribution board\/panel component rated up to 100A and must be installed and commissioned by a licensed electrician in accordance with UAE wiring regulations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat size board or application is the 100A CF485Z suited for?\u003c\/strong\u003e\u003cbr\u003eIts 100A rating and 6kA short-circuit rating make it suitable for main incoming protection on larger residential complexes, commercial buildings and light-industrial distribution boards where high-capacity earth-leakage protection is required.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Hager","offers":[{"title":"Default Title","offer_id":41797544837219,"sku":"CF485Z","price":353.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0570\/6570\/1475\/files\/CF485Z.webp?v=1786954880","url":"https:\/\/www.deluxeuae.com\/products\/hager-rccb-100a-4p-300ma","provider":"Deluxe Electricals","version":"1.0","type":"link"}
