Hai Bang Plateau type Single phase vacuum contactor are suitable for power systems with AC 50~60Hz, main circuit rated voltage 40.5kV, and rated current 160A, 250A, 400A, 630A. JCZ1 Single phase vacuum contactor is mainly used as a grounding switch when a single-phase ground fault occurs. JCZ1 Single Phase AC Vacuum Contactor is used in arc suppression cabinets and electrical occasions that require single-phase control. The altitude of the environment where the Single phase vacuum contactor Plateau type is used does not exceed 5000 meters above sea level, thus it is a plateau type vacuum contactor.
Types:
JCZ1-40.5TG/D-160
JCZ1-40.5TG/D-250
JCZ1-40.5TG/D-400
JCZ1-40.5TG/D-630
Application Condition:
1. Ambient Air Temperature: -25℃～+40℃,24-hour average must NOT exceed +35℃;
2. Altitude: 5000m or Lower; Our patent shows the JCZ1 plateau type single phase vacuum contactor can operate safely and stably within an altitude of 5000m above sea level.
3. Relative Humidity: Daily average less than 95%, Monthly average less than 90%, Must NOT exceed 50% when Ambient Air Temperature reaches +40℃;
4. Operation Environment: Ambient air shall not be contaminated by corrosive, flammable or explosive gas and water vapor, Contamination Level: Level III；
5. Installation of single phase plateau type vacuum Contactor:
When operating, the tilt angle between the surface of installed plateau type single phase vacuum contactor and the horizontal plane shall NOT exceed 5°.
Note: In case the above conditions cannot meet the user's requirements, the user can negotiate with the manufacturer for special treatment of the product.
