Sell Thermal Overload Relay (3UA)

Description

Product Description 3UA thermal relay is suitable for using in power system with AC *0Hz, rated operation voltage up to **0V and ***0V, in main circuit, current from 0.1A to **0A. 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 **5ºC to **5ºC 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 IEC****1, IEC****1 3UA*0 Rated operating current: *2.5A Rated insulation voltage: **0V Current setting range: 0.1A to *2.5A 3UA*2 Rated operating current: *5A Rated insulation voltage: **0V Current setting range: 0.1A to *5A 3UA*4 Rated operating current: *2A Rated insulation voltage: **0V Current setting range: 4A to *2A 3UA*8 Rated operating current: *0A Rated insulation voltage: ***0V Current setting range: *6A to *0A 3UA*9 Rated operating current: *3A Rated insulation voltage: **0V Current setting range: 0.1A to *3A 3UA*2 Rated operating current: **0A Rated insulation voltage: **0V Current setting range: *5A to **0A 3UA*6 Rated operating current: **0A Rated insulation voltage: **0V Current setting range: *0A to **0A 3UA*8 Rated operating current: **0A Rated insulation voltage: **0V Current setting range: **0A to **0A
