TDK-EPC has released a new series of EPCOS ThermoFuse varistors (ETFV) that are protected from overload and thus prevent fires. The ETFV series consists of a disk varistor of the AdvanceD series connected in series with a thermally coupled fuse and integrated in a package.
The thermo-fuse encapsulated in a special plastic disconnects an overheated varistor from the power circuit and thus prevents flames and smoke from developing. This increases the reliability of the equipment to be protected. Thanks to their thermal resistance and flame-retarding design, ThermoFuse varistors satisfy the specifications of UL 94 V-0. They are also qualified to UL 1449 3rd Edition, UL 60691 and IEC 6 0950-1 Annex Q.
In addition to the two terminal wires for the varistor, the EPCOS ETFV series has a third terminal that may be used to send warning signals – for example, to an LED to indicate that the fuse has been activated. The product range comprises disks with diameters of 14, 20 or 25 mm including the package.
The devices are designed to absorb maximum surge currents with an 8/20 μs pulse of between 6 and 20 kA at rated voltages of between 130 and 420 VRMS. They have a surge current capability of 20 kA and a maximum energy absorption capacity of 700 J for 2 ms. Applications include household appliances, power supplies, inverters for solar installations, and drives. They are also used for the general protection of electrical wiring and installations.
