Description:3UA series thermal overload 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 3 phase asynchronous
motor against overload and phase failure. 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 below 25 degree to above 55 degree 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, IEC60947-4-1.
