Power connector with overvoltage protection

摘要

A power connector for providing overload protection for an electrical operating station connected to a power mains, composed of at least one overvoltage arrester of a first type which is capable of quenching the power mains surge current and at least one overvoltage arrester of a second type connected in series with said arrester of the first type, with the insulation of one overvoltage arrester, in its unfired state, meeting the requirements of a basic insulation or of the supplementary insulation for a protective insulation, and both arresters being constructed for dissipating the pulses generated by a direct stroke of lightning or nuclear electromagnetic pulses without adversely affecting the protection afforded thereby.
