YUANKY thermal overload relay 660V 1000V 100A 50A 32A 12.5A 400A 630A 0.1A 25A three phase thermal relay switch

Short Description:

3UA Series Thermal Relay

Application

3UA series 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 relays have the test push- button for breaking NC contacts and the operating indication and free trip characteristics. The products also can be supplied with protecting case to ensure safety. The products can plug in the contactor and install independently or mount byrail.
