ABSTRACT:
A device for connecting, and then isolating and disconnecting an arrester includes a non-conductive housing with two electrical terminals. The housing has opposite ends separated by an internal chamber. The terminals are mounted at the housing ends. A resistor engages and extends between the terminals in the housing internal chamber. A cartridge with an explosive charge is mounted in the internal chamber adjacent the resistor. A gap spacer surrounds the cartridge, is adjacent one of the terminals and is spaced from the other terminal.
