External power supply required

EF45 are self-powered electronic 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 with their wide setting range, high accuracy, high operating temperature range and the option of choosing from 3 tripping classes (10E, 20E, 30E). The overload relays are connected directly to the contactors. Single installation sets are available as accessories. Manual or automatic reset can be selected, phase failure sensitivity according to IEC/EN 60947-4-1, temperature compensation, TEST and STOP function, tripped display on the front, trip and signal contact integrated (1 NO contact/1 NC contact).
