1.Therml Relay, Protect Open Phase Relay 
2.Rated Insulation Voltage: 660V/ 1100V 
3.Rated Current(max): 630A 
4.CE & Rohs

3UA series thermal relay is suitable for using in the 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 relays have the rest push - button for breaking NC contacts and the opertaing indication and free trip characteristics. The products also can be supplied with protecting case to ensure safety. The produsts can be plugged in the contactor and intalled independently or mounted by rail.
