Features
• Used as voltage-dependent resistors (VDR's) to protect electronic devices • They protect against overload build-up and protect valuable equipment from power surge damage • Surge voltages are absorbed in the varistor
Selection Criteria
• The maximum operating voltage must be lower than the varistor voltage.
