    摘要: An overvoltage protection device includes first (120) and second (130) electrically conductive electrode members and a varistor member (110) formed of a varistor material and electrically connected with each of the first and second electrode members. The overvoltage protection device includes both: an integral first fail-safe mechanism (161) configured to electrically short circuit the first and second electrode members about the varistor member when triggered by a first set of operating conditions; and an integral second fail-safe mechanism (141) configured to electrically short circuit the first and second electrode members about the varistor member when triggered by a second set of operating conditions different from the first set of operating conditions.

    摘要: A telecommunications system uses a breakout device to connect a primary power cable to different secondary power cables that connect to different remote radio units (RRUs). For example, the breakout device may include a power distribution terminal that connects -48VDC and return power lines in the primary power cable to different -48VDC and return power lines in the secondary power cables. In another example, the breakout device may connect a hybrid cable that includes both power lines and fiber optic lines. A surge protection system may be located in the breakout device to protect the RRUs and other electrical device from power surges. Alternatively, the surge protection system may be located in jumper power cables connected between the breakout device and the RRUs.
