Thermal Relay (3UA) 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 overleaping arrangement, for easy selecting by the customers from -25º C to +55º C air temperarature 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 IEC292-1, IEC337-1&VDE0660. 3UA50 Rated operating current: 12.5A Rated insulation voltage: 660V Current setting range: 0.1A to 12.5A 3UA52 Rated operating current: 25A Rated insulation voltage: 660V Current setting range: 0.1A to 25A 3UA54 Rated operating current: 32A Rated insulation voltage: 660V Current setting range: 4A to 32A 3UA58 Rated operating current: 80A Rated insulation voltage: 1000V Current setting range: 16A to 80A 3UA59 Rated operating current: 63A Rated insulation voltage: 660V Current setting range: 0.1A to 63A 3UA62 Rated operating current: 180A Rated insulation voltage: 660V Current setting range: 55A to 180A 3UA66 Rated operating current: 400A Rated insulation voltage: 660V Current setting range: 80A to 400A 3UA68 Rated operating current: 630A Rated insulation voltage: 660V Current setting range: 320A to 630A
