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

Ordering details

Description
The EF65, EF96 and EF146 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
2CDC231001F0012 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, 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
the contactors. The EF65, EF96 and EF146 have ATEX and IECEx certification .
