Abstract:
A surge protective device (SPD) module includes a module housing, first and second module electrical terminals mounted on the module housing, a gas discharge tube (GDT) mounted in the module housing, and a fail-safe mechanism mounted in the module housing. The GDT includes a first GDT terminal electrically connected to the first module electrical terminal and a second GDT terminal electrically connected to the second module electrical terminal. The fail-safe mechanism includes: an electrically conductive shorting bar positioned in a ready position and repositionable to a shorting position; a biasing member applying a biasing load to the shorting bar to direct the shorting bar from the ready position to the shorting position; and a meltable member. The meltable member maintains the shorting bar in the ready position and melts in response to a prescribed temperature to permit the shorting bar to transition from the ready position to the shorting position under the biasing load of the biasing member. In the shorting position, the shorting bar forms an electrical short circuit between the first and second GDT terminals to bypass the GDT.

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:
The active part which is provided for use in a surge arrester includes two connecting fittings, which are arranged along an axis at a distance from one another, at least one cylindrical varistor column, which is provided between the two connecting fittings, and at least one dielectric loop. This loop is supported on the two connecting fittings and thus holds the active part together, thus forming a contact force. The active part is distinguished by a small physical height and little use of materials. This is achieved in that at least one of the two connecting fittings has an electrode, which is arranged at right angles to the axis and is in the form of a plate, as well as an electrical connection, which is integrally formed on the plate. Furthermore, supporting means which are in the form of shoulders are provided for the dielectric loop, and are formed in the plate and/or are integrally formed at the edge of the plate.
