Double Power Supplies Wcq2g Automatic Intelligent Type Changeover Switch 50Hz 400V Transfer Switch
WCQ2G series MCB is one of updated type MCCBs researched and developed by the company by using advanced design and manufacture technology internationally.
WCQ2G series double power supplies automatic transfer switch (ATS) applies to AC50Hz, rated operation voltage 400V, rated operation current 16A to 2000A, to two circuits power supply of emergency power supply system. It can be set as manual of the mutual transfer between frequent-use and backup power supply, as circuit controlling switch of control, signal, and interlock functions. Some types of the product have communication ports to make it realisable of remote control and unattended substation to the user. Itapplies to residence community, hospital, mall, airport, etc.,
The ATS meets standards IEC/EN60947 and GB/T14048.11.
Model and meaning
Working environment
The WCQ2G automatic transfer switch works reliably under the following conditions:
Altitude not exceeding 2000 meters
Ambient temperature not higher than 40℃,not lower than-5℃,relative humidity not more than 95%.
No explosion hazardous medium environment
No rain or snow attack environment
Note:If the switch is expected to be used in conditions where the ambient air temperatureis higher than+40℃or lower than -5~-45,the user should explain to the manufacturer.
