LST Varistor Series SPD Thermally Protected Varistor
●The LST Varistor Series is constructed a built-in thermal disconnecting function and electric arc shield that help ensure safe operation during 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 & Benefits
●Short Circuit Current Rating (SCCR) of 200 kA and Nominal Discharge Current Rating (In) of 20 kA
●Available in both Maximum Discharge Current (Imax) ratings of 50 kA and 75 kA.
●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)
●Suitably rated for Type 1 and 2 SPD applications
●Same PCB footprint for 50 kA and 75 kA Imax rated 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
