Littelfuse LST Metal Oxide Varistors (MOVs)

Littelfuse LST Metal Oxide Varistors (MOVs) are constructed with Littelfuse's thermally protected varistor technology (TMOV). The built-in thermal disconnecting function and electric arc shield offer additional protection to prevent catastrophic failure and fire hazard, even under the extreme circumstances of varistor end-of-life or abnormal overvoltage conditions. These MOVs provide a visual tab option to display the LST working status. They feature the same footprint and PCB layout for Imax 50kA and 75kA options and an operating temperature range of -40°C to +85°C. Littelfuse LST MOVs are specifically designed for Type 1 and Type 2 Surge Protective Devices (SPDs) used in buildings, industrial motor controls, HVAC systems, and much more.
