Surge protection device

A surge suppression circuit with a thermal cutoff includes a first surge suppressor (Figl, 24) in series with a first thermal cutoff (22) device between a phase conductor and a neutral conductor. A second surge suppressor (44) in series with a second thermal cutoff device (42) is between the phase c...

Summary:A surge suppression circuit with a thermal cutoff includes a first surge suppressor (Figl, 24) in series with a first thermal cutoff (22) device between a phase conductor and a neutral conductor. A second surge suppressor (44) in series with a second thermal cutoff device (42) is between the phase conductor and a ground conductor. A third surge suppressor (34) is in series with a low temperature thermal cutoff device (12) between the neutral conductor and the ground conductor. The thermal cutoff temperature of the low temperature thermal cutoff device is lower than the thermal cutoff temperature of the first thermal cutoff device.
