The MOV-20DxxxK Series of 20 mm 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 1100 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.
