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 ex-
ternal 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). Fur-
2CDC231001F0012 ther features are the temperature compensation, trip contact (N.C.), signal contact (N.O.), auto-
matic or manual reset selectable, trip-free mechanism, STOP and TEST function and a trip indica-
tion. The overload relays are connected directly to the contactors. The EF65, EF96 and EF146 have

EF65-70 ATEX and IECEx certification (1).
