Isolation monitoring relay for non-grounded (IT) networks up to 400 V AC, 15-400 Hz

INSULATION MONITORING RELAY FOR UNGROUNDED (IT) NETWORKS UP TO 400 V AC, 15 - 400 HZ AND UP TO 600 V DC MEASURING RANGE 1 - 100/2 - 200 KOHM SUPPLY VOLTAGE AC/DC 24-240 V WIDTH 45 MM 1+1 OR 2 CO CONTACTS, SCREW Insulation monitoring relay with analog setting SIRIUS 3UG4 for monitoring non-grounded (IT) networks for insulation faults, e.g. in systems with strict requirements on availability (chemical industry, automobile manufacture, printing) in shipbuilding and the railway sector or in emergency power supplies. Worldwide use thanks to wide voltage supply range and international certificates. New predictive measurement principle allows very fast response times. Direct connection to networks with mains voltages of up to 690 V AC and 1 000 V DC by means of the 3UG4983-1A voltage reducer module The relay permits a permanent self-monitoring and manual test option. Reliable system diagnostics thanks to unambiguous error messages and connectable fault memory. Apart from devices for insulation monitoring of non-grounded alternating voltage networks, devices are also available for monitoring non-grounded DC and AC voltage networks, with screw terminals in each case. Available accessories comprise cover caps and a voltage reducer module for extending the range of measurement. SIRIUS relays - one range for every application.
