EF65, EF96, EF146 electronic overload relays – 20 to 150 A

Ordering details

The EF65, EF96 and EF146 are self-supplied electronic overload relays, which means no extra exter-
nal 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 elec-
tronic overload relay is convincing, above all, due to its wide setting range, high accuracy, high oper-
ational temperature range and the possibility to select a trip class (10E, 20E, 30E). Further features
2CDC231001F0012 reset selectable, trip-free mechanism, STOP and TEST function and a trip indication. The overload
are the temperature compensation, trip contact (N.C.), signal contact (N.O.), automatic or manual
relays are connected directly to the contactors. The EF65, EF96 and EF146 have ATEX and IECEx cer-

EF65-70 tification (1).
