They are easy to use like thermal overload relays and compatible with standard motor applications. Thanks to their wide range of adjustments, their high accuracy, high operating temperature range and the ability to select from 3 trigger classes (10E, 20E, 30E). The overload relays are connected directly to the contactor. Individual setup sets are available as accessories. Manual or automatic resetting selectable, phase failure sensitivity according to IEC/EN 60947-4-1, temperature compensation, TEST and STOP function, trigger display integrated on the front, trigger and signal contact (1 closer/1 opener).
