CPN Black Box Type 3 Class 3 Surge Arrester
A Class 3 surge arrester is a flexible solution to protect individual pieces of equipment. Perfectly suited to protect ring mains and individual sockets, switch fuse spurs, lighting, CCTV cameras, fire and alarm panels etc.
Its small size means that it can be mounted in confined spaces and an audible alarm will indicate if the arrester needs to be replaced.
The CPN Black Box offers 10 metres of protection either side of the device it is installed on.
