A disconnector is attached to and electrically in series with a surge arrester. The disconnector has a breakable shell that is broken by explosion of a cartridge within the shell when excessive current flows across an arcing gap. The disconnector has a top electrode and a bottom electrode with the top electrode connected to the surge arrester and the bottom electrode connectable to a connector wire. An annular electrically conductive elastomer gasket is compressed between the upper and lower electrode to provide a high resistance current path around the arcing gap and also to seal the cartridge from the outside atmosphere.
