An RCCB (residual current circuit breaker), also called an ELCB, monitors the balance of current between line and neutral conductors and disconnects the circuit when it detects earth leakage — protecting against electric shock and fire from insulation faults. The two devices protect against different fault types and are typically installed together on a distribution board.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat does the 300 mA sensitivity rating mean?\u003c\/strong\u003e\u003cbr\u003e300 mA is a higher-threshold sensitivity generally used for fire and equipment protection on larger distribution circuits, rather than direct personnel protection (which typically uses 30 mA devices). It trips on the larger leakage currents typical of insulation faults or equipment failure, reducing fire risk on sub-mains and distribution boards.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat does 4-pole mean and do I need it for this circuit?\u003c\/strong\u003e\u003cbr\u003eA 4-pole (3P+N) RCCB switches all three phase conductors and the neutral together. It's used on 3-phase, 4-wire circuits — typically main incomers or distribution boards feeding 3-phase loads — so both phase and neutral are isolated together on a leakage trip.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCan I install this myself?\u003c\/strong\u003e\u003cbr\u003eNo. This is a distribution board component that must be installed and connected by a licensed electrician in accordance with local wiring regulations. Incorrect installation of an RCCB can leave circuits without leakage protection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWill this fit a standard Hager distribution board?\u003c\/strong\u003e\u003cbr\u003eYes. The CFC441J is part of Hager's modular DIN-rail range and installs alongside Hager MCBs, isolators, and other DB accessories in a standard Hager consumer unit or distribution board.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n","brand":"Hager","offers":[{"title":"Default Title","offer_id":41797541691491,"sku":"CF441J","price":122.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0570\/6570\/1475\/files\/CFC441J.webp?v=1786954801","url":"https:\/\/www.deluxeuae.com\/products\/hager-rccb-40a-4p-300ma","provider":"Deluxe Electricals","version":"1.0","type":"link"}
