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.
