ABB MOTOR PROTECTION AND CONTROL 6/33

EF19, EF45 electronic overload relays – 0.10 to 45.0 A

Ordering details

The EF19 and EF45 are self-supplied electronic overload relays, which means no extra external
supply is needed. It offers reliable protection for motors in the event of overload or phase failure.
Easy to use like a thermal overload relay and compatible with standard motor applications, the
electronic overload relay is convincing, above all, due to its wide setting range, high accuracy, high
operational temperature range and the possibility to select a trip class (10E, 20E, 30E). Further
features are the temperature compensation, trip contact (N.C.), signal contact (N.O.), automatic or
manual reset selectable, trip-free mechanism, STOP and TEST function and a trip indication. The
overload relays are connected directly to the contactors. The EF19 and EF45 have ATEX and IECEx
1SBC101147F0010 certification (1). Short-circuit Trip class Type Order code Weight
