The EF750-800 is a self-supplied electronic overload relay designed to protect three-phase motors against overload and phase-failure conditions. Unlike separately powered electronic protection devices, it derives its operating power from the main circuit, eliminating the need for an additional external supply.

The relay provides a wide adjustable setting range of 250 to 800A, making it suitable for high-power motor applications. The user can select trip classes 10E, 20E or 30E according to the required motor starting and protection characteristics. It also incorporates temperature compensation, selectable automatic/manual reset, trip indication, STOP and TEST functions, and a trip-free mechanism.

The device connects directly to compatible ABB contactors, particularly AF580 and AF750, and is intended for industrial motor control and protection applications.
