General Introduction<\/strong><\/h3>\n

CKG3vacuum\u00a0contactor is mainly used in the power system with AC 50Hz and rated voltage 7.2kV, for making or breaking circuit and to make electromagnetic starter with suitable protective device and F-C switchgear.<\/p>\n

Working Conditions<\/strong><\/h3>\n

Altitude\u00a0above\u00a0sea\u00a0should\u00a0not\u00a0be\u00a0over\u00a01,000m;<\/p>\n

Ambient\u00a0temperature\u00a0is\u00a0-5~40\u00b0C;<\/p>\n

Average\u00a0temperature\u00a0in\u00a024\u00a0hour\u00a0limited\u00a0below\u00a035\u00b0C;<\/p>\n
