ABSTRACT:
A surge protector or arrester for providing surge protection for relatively low voltage or secondary equipment, circuits and systems includes a vertically stacked, parallel arrangement of two, independent, spark gap and valve block assemblies, the components of which are generally horizontally disposed within a triangularly shaped surge protector housing. The triangular shape of the housing enables maximum spacing of the three electrode contacts associated with the two assemblies to prevent their flashover while maintaining minimum exterior housing dimensions. The components of the two assemblies are disposed horizontally within the housing after a sealing and insulating compound has been applied to the entrance portions of the three contacts. Each of the three contacts includes an integrally formed crimp contact, an integrally formed lead-in electrode and an integrally formed spring contact. A plurality of novel spark gap electrodes and a plurality of expansion chambers, spaces or reservoirs are provided within the housing to enable hot, highly pressurized, ionized gases formed during the discharge operation of one or both of the assemblies to expand and cool to thereby prevent flashover of two or more of the contacts.
