3UA Thermal Relay
  
Application:

  3UA thermal relay is suitable for using in power system with AC 50Hz,rated operation voltage up to 660V and 1000V,in main circuit,current from 0.1A to 630A.It
is used to protect AC three phase asynchronous motor against overload and phase failure.
  The current setting value can be regulated and the setting current values of many thermal elements are intercrossing overlepping arrangement,for easy selecting by the customers from——25~C to+55~C air temperature as the products have temperature compensating.The relays have the test push—button for breaking NC contacts,the operating indication and free trip charactristics.The items conform to IEC292-1,IEC337-1 & VDE0660.
