Definitions

  • the display member 50 is preferably formed by two panels 510, 520 which, when the two varistors 10 are in service (FIG. 5a), are both substantially opposite a window 61 formed in the wall 60B of the housing 60.
  • the protection device according to the invention can also be equipped with remote signaling means, allowing a third party to view the state of the varistors remotely.
  • remote signaling means are well known to those skilled in the art and will not be the subject of a more detailed description.
  • the invention finds its industrial application in the design and manufacture of surge protection devices.
