AM3SE Medium Voltage Overload

Description

The NEPEAN AM3SE relays have been designed with the intent to control, protect and monitor industrial installations, public distribution networks and substations. Furthermore, they can be applied to be used as part of a protection scheme for transformers and generator transformers. Additionally, they provide back-up protection for HV and EHV transmission systems.
