Both versions are comprised of radial leaded MOVs (Metal Oxide V aristors) with an integrated thermally activated element designed to open in the event of overheating due to the abnormal overvoltage, limited current, conditions outlined in UL1449. T he TMO V® and iTMOV® varistor’s integrated thermal element, in conjunction with appropriate enclosure design, helps facilitate SPD module compliance to UL1449 for both cord connected and permanently connected applications. The TMO V ® and iTMOV® varistors offer quick thermal response due to the close proximity of the integrated thermal element to the MOV body. T he integrated configuration also offers lower inductance than most discrete solutions resulting in improved clamping performance to fast overvoltage transients. The iTMOV® varistor differs from the TMO V® varistor by the inclusion of a third lead for the purpose of indicating that the MOV has been disconnected from the circuit. T his lead facilitates connection to monitoring circuitry. Additionally TMO V® and iTMOV® varistors are wave solderable, thus simplifying end product assembly by reducing the the expense and rework associated with hand soldering operations.
