E16DU, EF19, EF45 electronic overload relays – 0.10 to 45.0 A

Ordering details

The E16DU, 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.),
2CDC231001F0007 indication. The overload relays are connected directly to the contactors. The EF19 and EF45 have
automatic or manual reset selectable, trip-free mechanism, STOP and TEST function and a trip
ATEX and IECEx certification (1).
