Product Description
To Supply 12.5A 25A 3UA50 3UA52 Electromagnetic Thermal Overload Relay 0.1A~12.5A 0.1A~25A
Application
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 thermal elements are intercrossing overlapping arrangement, for easy selecting by the customers from -25°Cto +55°C air temperature 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 IEC60947-5.
Characteristic
Three-phase thermal relays with release class 10A.
With differential phase-failure protection.
With continuous current adjusting scale.
With temperature compensation.
With ON/OFF indicator.
With Manual/Auto reset button.
With Auxiliary contacts 1 NO+1 NC insulated each other.
Mounting: Plug in connection with contactor or install as a single unit.
The altitude couldn't exceed 2000m.
Ambient temperature: -5 ~+55 degree centigrade and the average temperature no more than +35 degree centigrade in 24 hours.
Atmosphere: Comparative humidity no more than 50% at max +40 degree centigrade, and it may be higher at a lower temperature. The lowest average temperature no more than +20 degree centigrade in the wettest month.
The maximum average comparative humidity of this month could not exceed 90%, The change of temperature leading to dew on the product must be considered.
