Abstract: A circuit protection device includes an overvoltage monitor circuit that is operable to monitor a power supply circuit to detect an overvoltage condition on the power supply circuit and to change a state of an overvoltage output responsive to the overvoltage condition on the power supply circuit. A bi-directional switch is operable to interrupt or limit current flow though the power supply circuit responsive to the change in the state of the overvoltage output. A bi-directional voltage limiter is connected across output terminals of the circuit protection device and is operable to limit an overvoltage to a predefined voltage limit.

Abstract: A surge suppression system provides surge protection both locally within the radio station building were the power plant and telecommunication equipment are located and remotely next to the radios and antennas located outside of the building on the communication tower. An external surge suppression unit provides a waterproof enclosure for both surge suppression devices and fiber optic connectors. A rack mountable surge suppression unit provides local in-line surge suppression protection for the electrical equipment located in the communication station. A unique surge suppression tray is hot swappable so that multiple surge suppression devices can be replaced at the same time without disrupting radio operation. Pluggable surge suppression modules can be used in both the external surge suppression unit and the rack mountable surge suppression unit.

Abstract: A connection lug comprises an electrically conductive body, an electrically conductive blade connector extending from a first end of the body, and a cable hole located in a second end of the body configured to receive a cable. A clamping cam in the connection lug may rotate inside of the body and clamp against the cable. A screw hole may be configured to receive a clamping screw. A portion of the clamping cam may extend into the screw hole and insertion of the clamping screw into the screw hole may push against the portion of the clamping cam and rotate the clamping cam into the cable hole.

Abstract: An overvoltage protection device includes first and second electrically conductive electrode members, a varistor member formed of a varistor material and electrically connected with each of the first and second electrode members, and an electrically conductive, meltable member. The meltable member is responsive to heat in the device to melt and form a current flow path between the first and second electrode members through the meltable member.

Abstract: An overvoltage protection assembly includes a rail and a mount device. The mount device includes a base member having front and rear opposed surfaces and a mounting structure on the rear surface. The mounting structure secures the base member to the rail. An overvoltage protection module is mounted on the front surface of the base member.
