1220-20-I4-480M2

1220-20-I4-480M2 is a 1220 series thermally protected metal oxide varistor (TPMOV) surge protective device. This surge suppressor with thermal protection is designed to open in the event of overheating due to an abnormal overvoltage or temporary overvoltage (TOV) and will interrupt any abnormal current that may be encountered, up to rated limits. Applications include surge protection devices, AC-DC distribution, all power circuits, telecommunications, built-in surge protection of electronic equipment.
