LST Varistor Series Metal Oxide Varistors (MOVs)

PublishTime：2021-05-28

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 prevent catastrophic failure and fire hazard even under the extreme circumstances of varistor end-of-life or abnormal overvoltage conditions. It is specifically designed as a Type 1 Component Assembly Surge Protective Device (SPD) and is suitable for Type 1 and Type 2 SPDs.
●Features:
■Short Circuit Current Rating (SCCR) of 200 kA andNominal ■Discharge Current Rating (In) of 20 kA.
■Available in both Maximum Discharge Current (Imax) ratings of 50 kA and 75 kA. Both ratings utilize the same footprint and PCB layout.
■Mechanically triggered AC and DC rated micro-switch with Normally Open or Normally Closed options for remote indication and/or monitoring circuit.
■Visual tab option to display LST working status.
■RoHS compliant, Lead-free, and Halogen-free.
■UL Recognized to UL 1449 and CSA C22.2 No. 269.4 as a Type 1 Component Assembly (Type 1CA).
●Benefits:
■Suitably rated for Type 1 and 2 SPD applications.
■Same PCB layout/design for 50 kA and 75 kA Imaxrated SPDs.
■More flexibilities/options for designing an isolated remote indication/monitoring circuit.
■Clear indication for technician/engineer to replace EOL product to continue surge protection for the end product.
■Environment-friendly.
■Facilitate meeting UL 1449 or CSA C22.2 No. 269.1 and 269.2 for Type 1 or Type 2 SPDs .
