LST Varistors

The LST Varistor Series is constructed with Littelfuse’s renowned thermally protected varistor technology (TMOV). The built-in thermal disconnecting function and electric arc shield provides additional protection to prevent catastrophic failure and fire hazard even under the extreme circumstances of varistor end-of-life or abnormal overvoltage conditions. It is specifically designed for Type 1 and Type 2 Surge Protective Devices (SPDs).
