25kA TPMOV (Thermally Protected MOV)

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
disc making the TPMOV a fail-safe device. 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. Mersen’s
25TPMOV is rated for 25kA - 8/20μs peak surge current and is
available for maximum continuous operating voltages (MCOV) from
150V to 320VAC.
