General Characteristics

General Information

The MOV-20DxxxK Series of 20mm radial leaded varistor devices protects against overvoltage transients such as lightning,

power contact and power induction. The metal oxide varistors offer a choice of varistor voltages from 18 V to 1800 V and Vrms

voltages from 11 V to 1000 V. The devices have a high current handling, high energy absorption capability and fast response

times to protect against transient faults up to rated limits.
