The IED-EP+ S16 series is part of the EuroProt+ Smart Line numerical protection relay. Members of the Smart Line also offer a wide range of functions but they do so in a small, compact enclosure so that they can be installed in locations with limited space available for the protection equipment.
The IED-EP+ S16 series contains a special selection of the EuroProt+ modules, bearing in mind the cost effective realization. The low-cost IED-EP+ S16 series was able to be realized with predefined hardware arrangement and fixed standard configurations.

The IED-EP+ S16 is available in five predefined standard configurations to suit the most common feeder protection applications. Available configurations of the S16 series:
♦ Variant 1 is mainly used as main or backup overcurrent protection.
♦ Variant 2 provides additional motor protection functions compared to Variant 1.
♦ Variant 3 is suitable for those application where only voltage and frequency based protection functions are required.
♦ Variant 4 is extended with one voltage input. It can be used for residual voltage measuring. Consequently, the Variant 4 application includes the residual directional overcurrent protection function.
♦ Variant 5 provides motor protection functions above Variant 4.
The configured protection functions of each predefined standard configuration are listed in the table below:
