- Self-supplied devices
The EF370 is an 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,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.
