3UA Thermal Overload Relay

Application

3UA series thermal overload relay is suitable for using in power system with AC 50/60Hz, rated operation voltage up to 660V and 1000V, 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 customers from -25Ûc to +55Ûc 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 characteristics. The items conform to IEC60947-5.
