Abstract:
1. A device for remote monitoring of the state of a surge protector having at least a single pole, comprising: a bracket, and a slide-in protective member associated with each pole of the surge protector; a suspended positioning element mounted for reciprocal movement in the bracket, the positioning element having an indicating end engaged with the slide-in protective member in operational connection of the surge protector to an electrical circuit, and an opposite end with a flange configured thereon, the suspended positioning element configured to move relative to the bracket upon a status change of the slide-in protective member causing the slide-in protective member to disengage from the indicating end of the suspended positioning element; a signaling plate having a first end pivotally mounted in the bracket, and an opposite free end disposed in the path of movement of the flange on the suspended positioning element so as to be engaged by and pivoted by the flange; a switch mounted in the bracket, the switch having a control element activated by engagement of the free end of the signaling plate after the status change of the slide-in protective member causing generation of an electrical signal indicating a change of protection status of the surge protector.
