The Mersen Thermally Protected MOV has been developed to assist in eliminating the failure characteristics of Metal-Oxide-Varistors. The TPMOV is a fail-safe device. It is composed of a voltage clamping device and a disconnecting apparatus that monitors the status of the metal-oxide disk. In the event that the disk is approaching breakdown it is effectively disconnected from system power. The TPMOV is rated for 40ka of 8/20microses surge current. The TPMOV ratings are available from 150V to 550V. The TPMOV has been designed with two built in isolated indicating features. The first is a visual indicator. When the unit has disconnected from system power, two isolated pins will be noticed atop the TPMOV enclosure. The second feature is a remote indicator composed of a N/O micro-switch. In the event that the TPMOV has disconnected system power the switch will change status. These features lower costly engineering time that would be required for traditional MOV products. LAYOUT: The TPMOV footings are similar to that of equivalent voltage ratings of traditional 25 to 40mm MOV's. The TPMOV can be utilized on existing systems that utilize traditional MOV's without costly board redesigns.

Ratings: 150-550VAC
