Varistors With Thermal Disconnection / VTD

VTD

 The VTD(S) Varistors with Thermal Decoupler use standard radial-lead metal oxide varistors equipped with a thermal decoupling device. They are widely used in TVSS products, AC/DC power supplies, AC panel protection modules, AC line power supplies, surge protected strip connectors, AC power meters, UPSs (Uninterruptible Power Supplies), inverters, white goods, GFCIs (Ground Fault Current Interrupters). The advantages of the VTD(S) Varistors with Thermal Decoupler are: leads construction for PCB mounting, a thermal decoupling device which protects the VTD(S) from varistor failure in the event of abnormal overvoltage and can withstand 16Amps, the VTD(S) also has the remote signalization capability.
