| 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 open-phase.
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 customeis from -25 to 55 air
temperature as the products have temperature compensating,The
relays have the test push-putton of breaking NC contacts,the operating
indication and free tripcharacteristics.The items confrom to
IEC292-1,IEC337/1 & VDE0660. |  |
