Mersen TPMOV (Thermally Protected MOV) 150TPMOVTS

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 disc 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. TPMOV7: 50% more surge capacity, Same footprint The TPMOV7 is rated for 75kA - 8/20?s peak surge current and is available for maximum continuous operating voltages (MCOV) from 150V to 320VAC. Features Industry-leading, patented TPMOV technology available in 50kA and 75kA surge capacities Consistent footprint with 25–40mm MOVs Built-in visual/remote indication optional Wave solderable No additional overcurrent protective device (fuses) required
