World Products, LLC TVZ series is a two or three-leaded
Thermally Protected Metal Oxide Varistor
One lead of the TVZ varistor is connected to a thermal link which is designed to open when the varistor is under sustained
abnormal over-voltage conditions. The TVZ series is designed to meet the abnormal over-voltage requirements of UL 1449 3rd
edition, Section 39.4.
Traditional Metal Oxide Varistors were originally designed to protect equipment from surges at the specified rated voltage, but
Metal Oxide Varistors may fail to a short-circuit condition or fail to open when subjected to sustained steady-state over-voltage
above its rated specifications. TVZ has a thermal link integrated with an MOV disk that responds to the MOV temperature and
disconnects the MOV from the line, should the temperature or voltage exceed a certain level.
World Products, LLC three-leaded device is designed to be connected, via the monitor lead, to an indicator (such as an LED) to
provide diagnostic features indicating if the MOV is disconnected from the circuit in the event the thermal link element opens.
As a result of the integration of the thermal link attached to the MOV disc, Thermally Protected Varistors provide an instant
response to unexpected over-voltage situations. World Products, LLC Thermally Protected Varistors offer protection to sensitive
downstream electric components.
Additionally, TVZ varistors are wave solderable which simplifies end product assembly by reducing the expense and rework
associated with hand soldering operations.
CAUTION:
Thermally Protected Varistors are intended, in conjunction with appropriate enclosure design, to help facilitate
SPD module compliance to UL 1449. Under extreme abnormal over-voltage conditions, some units will exhibit substantial
heating, arcing and venting prior to opening. Modules must be designed to contain this possibility. Application testing is strongly
recommended.
Proper design of surge protective devices (SPD’s) require that they meet new UL1449 3rd Edition requirements for
abnormal over-voltage limited current. Fuses that are meant to protect the system for large fault currents do not address
the need to protect against low fault currents. These low fault currents can result in catastrophic failure prior to tripping
the higher current fuse. TVZ series varistors can meet the needs of the SPD designer, avoiding having to create a
complicated/high cost approach.
The thermo link in a thermally protected varistor should never be used in series with the load. It is only used to provide
protection to the varistor portion in case of an abnormal over voltage condition.
