AC high voltage vacuum contactor (plateau type)

Unit: SET

Size: JCz1-(7.2or12)TG/D160~1250

Price: FOB SHANGHAI

1. Product introduction

This series of products is dedicated to plateau type, suitable for power systems with AC 50~60Hz, main circuit rated voltage 7.2kV, I2kV, and rated current 160A~1250A respectively, mainly used as a grounding switch when a single-phase grounding fault occurs. It is used in arc suppression cabinets and electrical occasions that require single-phase control. The altitude of the product's operating environment does not exceed 5000 meters.
