O/L relay 1 maker ABB EF45-45 1 pc(s)

EF45 are self-powered solid-state overload relays that do not require an additional external power supply. They reliably protect motors in the event of an overload or phase failure. Like thermal overload relays, they are easy to use and compatible with standard motor applications. They impress thanks to their wide setting range, their high accuracy, the high operating temperature range and the possibility of selecting from 3 trigger classes (10E, 20E, 30E). The overload relays are connected directly to the contactors. Stand-alone installation sets are available as accessories. Manual or automatic reset selectable, phase failure sensitivity according to IEC/EN 60947-4-1, temperature compensation, TEST and STOP function, trigger display on the front, trigger and signal contact integrated (1 NO/1 NC).
