Overview
• Combined test and reset button
• Multi-color LED for operating, fault and status messages
• Exchangeable electronic module without mechanical separation of the primary conductors
• Extension/retrofitting or modification of functions for changed monitoring requirements
• Load current insensitive by magnetic full screen (only CTUB10xCTBC20P…210P)
• Connection monitoring of the measuring current transformer
• SUPPLY VOLTAGE DC ±12 V/DC 24 V.
• CTUB10x-CTBC20…210 for the RCMS460/490 series differential current monitoring systems and the Differential current monitoring device RCMA420/423
• CTUB10x-CTBC20P…210P for RCMS460/490 series differential current monitoring systems and RCMA420/423 differential current monitoring devices. Can be used with very high peak load currents due to plant conditions.
• CTUB104-CTBC20…210(P) for EDS440 and EDS441LAB series insulation fault detectors
