Overvoltage cut off properties of DSSV type

Part number DSSV-301L-YD, DSSV-401M-YD
Applied conditions AC600V-40A-1.50sec. AC600V-7A-5sec. AC600V-2.2A-30min.
Rate of ignition n=100 0 0 0

Overvoltage testing is required in both UL60950 and CSA-C22.2 No.225-M90.
The DSSV is effective in protecting against these overvoltage conditions by opening the circuit.
