  • Surge protective device with contoller
    Patent number: 8929042
    Abstract: A surge protective device is disclosed that may include a comparator to determine when a line voltage of a line is above a threshold. The device may include a switch to couple a clamping device to the line voltage when the comparator determines the line voltage is above a threshold, wherein the clamping device shunts current from the line. The switch may include a silicon-controlled rectifier (SCR) or a thyristor and the clamping device may include a selenium surge suppression device.
    Type: Grant

    Date of Patent: January 6, 2015
    Assignee: Thomas & Betts International, Inc.
    Inventors: Hans-Erik Pfitzer, Martin William Guy
  • Surge protective device with thermal decoupler and arc suppression
    Patent number: 8502637
    Abstract: A device may include a metal-oxide varistor (MOV), wherein the MOV increases in temperature as a voltage applied across the MOV exceeds a rated voltage. The device may include a first conductor contacting the MOV and a second conductor contacting the MOV. The second conductor may be configured to disconnect from the MOV when the MOV reaches a threshold temperature. The device may include an enclosure to surround the MOV, the first conductor, and the second conductor, wherein the enclosure includes a non-conductive fluid to suppress arcing.
