ABSTRACT:
A clip-on device to protect telephones and communication apparatus, wherein clips for releasably holding a 3-terminal gas protector are external extensions of electrically insulated spaced terminals within the housing. A heat coil in series with each communication line and a carbon block air gap protector across each half of the gas protector for redundancy, are within the housing. The heat coil protects against a sustained overcurrent condition on the line while the gas and air gap protectors ground over-voltages of short duration. Utilizing heat conduction means, heat generated from sustained over-voltage melts a fusible disc allowing spring biased parts within the housing to move and short line terminals to ground.
