EF750 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 large setting range, high accuracy, high operating temperature range and the option of choosing from three trip classes (10E, 20E, 30E). Other features include temperature compensation, integrated trip and signal contact (1 NC/1 NO), automatic or manual selectable reset, trip-free, STOP and TEST function and tripped display on the front. Rail kits are available as accessories for contactor mounting. EF460 have an ATEX certification.
