A surge suppressor module includes a power conductor, a ground conductor, and a housing including an opening and a plurality of dovetail groove mechanisms and arcuate ground bus bars for electrically and mechanically mounting a corresponding surge suppressor module. An alternating current surge suppressor circuit is housed by the housing. The circuit receives the power and ground conductors through the opening of the housing. The circuit electrically connects the ground conductor to the plurality of arcuate ground bus bars for electrically and mechanically mounting a corresponding surge suppressor module, in order to provide a common ground connection thereto.

Modular surge suppressor system and surge suppressor module

A surge counter/detector apparatus includes current sensors communicating with power lines to sense a surge condition. A trigger circuit communicates with the current sensors and outputs a first signal in response to the sensed surge condition. The trigger circuit is reset and enabled by a second signal in order to enable subsequent output of the first signal. A processor detects the first signal from the trigger circuit and responsively increments and displays a count value at a display. The processor provides the second signal having a first state to reset the trigger circuit and a second state to enable the trigger circuit. The processor includes a timer to vary a time between (a) detecting the first signal, and (b) resetting and enabling the trigger circuit.

Surge counter/detector apparatus, system and method

A surge protection device includes terminals adapted to receive a power source voltage and surge protection circuits, each of which includes a thermal fuse spring, one or more metal oxide varistors (MOVs), and one or more fuse traces corresponding to the MOVs. The thermal fuse spring, one of the fuse traces and the corresponding one of the MOVs are electrically interconnected in series between the terminals, in order to form a series electrical connection therebetween. The thermal fuse spring is adapted to disconnect the series electrical connection between the terminals under first fault conditions including a first current of first duration through one of the MOVs. The thermal fuse spring and each of the fuse traces are adapted to cooperatively disconnect a corresponding one of the series electrical connections between the terminals under second fault conditions including a second greater current of second lesser duration through one of the MOVs.
