NAS network and system protection

The compact, plug-and-play network and system protection combinations from Eaton’s Moeller series are suitable for systems from 30 kVA to 130 kVA and come in a plastic housing with IP65 protection. Both ranges meet the requirements of VDE-AR-N 4105:2018-11. The devices consist of one or two contactors connected in series, which are controlled via an NA protection relay and come pre-wired and mounted in an enclosure. The network and system protection combinations are intended for installation between the inverter and the mains connection.
