25kA - 25mm TPMOV (Thermally Protected MOV)

Mersen’s TPMOV technology eliminates common failure
modes that occur in the field with standard metal oxide varistors.
Internally each component is comprised of a voltage clamping device and
a disconnecting apparatus that monitors the status of the metal oxide
disc making the TPMOV surge suppression component a fail-safe device. Upon failure the TPMOV surge suppression component is
also equipped with a visual pin indicator as well as a normally open
micro-switch providing remote indication, if applicable. Mersen’s
25TPMOV series surge suppression component is rated for 25kA - 8/20μs peak surge current and is
available for maximum continuous operating voltages (MCOV) from
150V to 320VAC.
