This electronic overload relay is easy to use, similar to a thermal overload relay and compatible with standard motor applications. It offers a wide setting range, high accuracy and can be selected with trip classes (10E, 20E, 30E). Additional features include temperature compensation, trip contact (NC), signal contact (NO), selectable automatic or manual reset, trip-free mechanism, STOP and Test functions and trip indication. The overload relays are directly connected to the contactors. Single mounting kits are available as accessories.
