ABB ELEC O/L RELAYS 375-1250A EF1250DU-1250

The E1250DU is a self-supplied electronic overload relay that does not require an external power supply. It provides reliable protection for motors in case of overload or phase failure. This electronic overload relay is easy to use, similar to a thermal overload relay, and is compatible with standard motor applications. It offers a wide setting range, high accuracy, and can be used in high operational temperature conditions. Additionally, it allows for the selection of trip classes (10E, 20E, 30E). Other features include temperature compensation, trip contact (N.C.), signal contact (N.O.), selectable automatic or manual reset, trip-free mechanism, STOP and TEST function, and trip indication. Busbar kits are available as accessories for contactor mounting.
