  • Fireproof cover for household electrical distribution boxes

    Fireproof cover for household electrical distribution boxes

    3M™ Fire Barrier Electrical Box Inserts are a flexible, one-piece fire-rated intumescent insert used to protect electrical boxes by adhering to the inside the box. When exposed to fire, the insert expands to fill up the box preventing the spread of fire and limiting temperature rise. To protect against overheated ECUs, we've manufactured an ECU fire protection system consisting of an ECU cover housed with intumescent lining. Other sizes can be made to order. Available as Ex certified (Sira 08 ATEX 3212 or IECEx SIR 13. 0038X and fitted with an M6 earth stud). Tested to meet Amendment 3 to BS7671:2008.
