Product Description

3UA THERMAL OVERLOAD RELAY 
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 ther

mal elements are intercrossing overlepping arrangement, for easy selecting by the cus

tomers 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 oper

ating indication and free trip characteristics. The items conform to IEC60947-5.
