High Voltage HEL ZOV Blue Radial Leaded 20mm Disc VDR Varistor 20D471K 470V 10% 4.5KA High Surge Type 350J Available
General Information
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.
