Product Description
Features:
1) Suitable for using in power system with AC 50Hz, rate operation voltage up to 660V
and 1,000V, in main circuit, current from 0.1A to 630A. It is used to protect AC three-
phase asynchronous motor against overload and open-phase
2) The current setting value can be regulated and the setting current values of many
thermal elements are intercrossing overlapping arrangement, for easy selecting by
customers from -25oC to 55oC air temperature as the
products have temperature compensating.
3) The relays have the test push-button for breaking NC contacts, the operating
indications and free trip characteristics
4) Conforms to the IEC60947-4 standard
