Littelfuse LST5505VL2NT1 Datasheet & Stock

LST series Metal Oxide Varistors (MOVs) are 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. Mechanically triggered AC and DC rated micro-switch with Normally Open or Normally Closed options for remote indication/monitoring circuit. It is specifically designed for Type 1 and Type 2 surge protective devices (SPDs).
