An Ingress Protected Fuse Connection Unit, fitted with a 13A fuse link to BS 1362. Master seal Plus has been specifically developed for use in both outdoor and indoor environments, and where wiring devices and accessories would be at risk from penetration by dust or water. With a rating of IP66, Master seal Plus offers total protection against dust, and is protected against high pressure jets of water from any direction. Master seal Plus sockets can seal around virtually any standard 13A plug including moulded plugs, allowing safe connection for any appliance. An improved catch eases the opening and closing of the lid, whilst ensuring the integrity of the seal. The seal is fixed to the mounting frame of the product, enabling rapid installation, and removing the risk of error when placing a floating gasket.
