Further details: The EF19 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 are impressive thanks to their wide setting range, high accuracy, high operating temperature range, and the option of selecting from three tripping classes (10E, 20E, 30E). The overload relays are connected directly to the contactors. Individual installation sets are available as accessories. Manual or automatic reset selectable, phase failure sensitivity in accordance with IEC/EN 60947-4-1, temperature compensation, TEST and STOP function, tripped indicator on the front, integrated tripping and signalling contact (1 NO/1 NC contact).
