EF205, EF370 electronic overload relays – 63 to 380 A

Ordering details

The EF205 and EF370 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 elec-
tronic overload relay is convincing, above all, due to its wide setting range, high accuracy, high opera-
tional 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
2CDC231010V0012 are connected directly to the contactors. The EF205 and EF370 have ATEX and IECEx certification (1).
