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

Ordering details

Description
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
2CDC231001F0007 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
