An RCCB like this one protects against earth leakage by monitoring current imbalance and disconnecting the circuit — the two are complementary and are normally installed together in a distribution board.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat does the 300mA sensitivity rating mean?\u003c\/strong\u003e\u003cbr\u003e300mA RCCBs are sized for fire and equipment protection on larger circuits and sub-mains, not personal shock protection — that requires a 30mA device. A 300mA unit is a common choice as a main incomer or sub-distribution protection device upstream of 30mA final-circuit RCDs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHow many poles do I need?\u003c\/strong\u003e\u003cbr\u003eA 4-pole (4P) RCCB switches all three phases plus neutral together. Use 4P for three-phase supplies or distribution boards where the neutral must also be isolated; 2-pole devices are used for single-phase circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCan this be used alongside MCBs in the same board?\u003c\/strong\u003e\u003cbr\u003eYes. This RCCB is typically installed upstream of the MCBs it protects, on the same DIN rail, so a leakage fault trips the RCCB while overloads\/short circuits are still cleared by the individual MCBs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCan I install this myself?\u003c\/strong\u003e\u003cbr\u003eNo. RCCBs are wired into a live distribution board and must be installed by a licensed electrician in line with UAE wiring regulations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c\/div\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":41797519638627,"sku":"F204 100A\/0.30","price":363.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0570\/6570\/1475\/files\/IMAGE-EDIT_a27f5d89-5a78-44c2-b88c-7b6e212fbef0.png?v=1786954782","url":"https:\/\/www.deluxeuae.com\/products\/abb-elcb-rccb-100a-4p-300ma-f204","provider":"Deluxe Electricals","version":"1.0","type":"link"}
