Overvoltage Protection - Thermally Protected Metal-Oxide Varistor
TPMOV® UL Type 1 - 34MM - 50kA

Mersen's patented TPMOV® (Thermally Protected Metal Oxide Varistor ) eliminates common destructive failure modes associated with standard MOVs. Comprised of a voltage clamping device and a disconnecting apparatus that monitors the status of the metal oxide disk inside the TPMOV, the device is securely disconnected in the event of an overvoltage by an arc shield. Upon failure, the TPMOV is also equipped with a visual pin indicator as well as a normally open microswitch providing remote indication, if applicable. Read more
TPMOV® UL Type 1 - 34MM - 75kA

50% More Surge Capacity – Same Footprint Mersen’s patented TPMOV technology eliminates common failure modes that occur in the field with standard metal oxide varistors. Internally the TPMOV is comprised of a voltage clamping device and a disconnecting apparatus that monitors the status of the metal oxide disk making the TPMOV a fail-safe device. In the event of an overvoltage breakdown the metal oxide disk is securely disconnected from the system power by an arc shield. Upon failure the TPMOV is also equipped with a visual pin indicator as well as a normally open micro-switch providing remote indication, if applicable. The TPMOV7 is rated for 75kA - 8/20μs peak surge current and is available for maximum continuous operating voltages (MCOV) from 150V to 320VAC. Read more
