ABB EF19-18.9

EF19 are self-sufficient electronic overload relays that do not require an additional external power supply. In the event of an overload or phase failure, they reliably protect motors. They are easy to use, like thermal overload relays, and are compatible with standard motor applications. They impress with their wide adjustment range, high accuracy, broad operating temperature range, and the option to choose from three tripping classes (10E, 20E, 30E). The overload relays are connected directly to the contactors. Standalone kits are available as accessories. Manual or automatic reset options are selectable, phase failure sensitivity according to IEC/EN 60947-4-1, temperature compensation, TEST and STOP functions, triggered indicator on the front, integrated tripping and signal contact (1 normally open/1 normally closed).
