ABB EF750-800 O/L relay 1 maker 1 pc(s)

EF750 are self-powered solid-state overload relays that do not require any 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 large setting range, their high accuracy, the high operating temperature range and the possibility of selecting from three trigger classes (10E, 20E, 30E). Other features include temperature compensation, integrated trigger and signal contact (1 NC/1 NO), automatic or manual selectable reset, free release, STOP and TEST function as well as trigger display on the front. Rail kits are available as accessories for contactor mounting. EF460 have an ATEX certification.
