Product Details

Thermal (MOV) Varistor OBV-TMOV Series

OBV-TMOV types are heavy-duty metal oxide varistors with thermal cutoff device. This device protects OBV-TMOV types from varistor failure in the event of abnormal overvoltage. They offer excellent surge protection with extra safety for various electronic equipment such as: traffic and railway protection, waterworks, communication equipment, automatic control devices for power distribution, oil drilling and mining equipment. 

The advantages of the OBV-TMOV series are: terminals construction for PCB mounting, a thermal cut-off device which protects OBV-TMOV types from varistor failure in event of abnormal over voltage or varistor thermal runaway. Remote signalization can be achieved by external circuitry
