Max. Operating Voltage, AC: | 250V |
Varistor Voltage at 1 mA: | 350V |
Max. Surge Current: | 1200A |
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. |
