Monitoring Relays

400 IM Series

In practical operation, the broad field of application for measuring and monitoring relays can be devided into 2 areas. Appliances of the series 400 (housing width 22,5 and 45 mm) are used for industrial applications (fitting in service cabinets); appliances of the IM-series (housing width 35 mm, equipped to fit the installation distribution panel) are inserted for applications in installation zones.
Both series are equipped with versatile functionality: current monitor AC, DC; voltage monitor one and three-phase; phase sequence and phase monitor, asymmetry monitor in three- and four wire networks.
Especially for the installation zone: undervoltage monitor for systems according to VDE 0107/0108 (VDE – Association of German Electrotechnical Engineers) and thermistor monitor (temperature monitoring for transformers and electrical motors).
