EF205, EF370 electronic overload relays – 63 to 380 A

Ordering details

Description
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 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,
2CDC231010V0012 and TEST function and a trip indication. The overload relays are connected directly to the contactors. The
trip contact (N.C.), signal contact (N.O.), automatic or manual reset selectable, trip-free mechanism, STOP
EF205 and EF370 have ATEX and IECEx certification .
