The 7 mm radial leaded varistor MOV-07DxxxKC Series protects against overvoltage transients such as lightning, power contact and power induction. The metal oxide varistors offer a choice of varistor voltages from 200 V to 820 V and Vrms voltages from 130 V to 510 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.
