Smart, all-current sensitive residual current monitors (Type B) reliably detect fault and differential currents and report them without shutting down the system. The Ethernet interface transmits the measured differential current values via Modbus-TCP protocol. The smart residual current monitors are an integral part of the e.Guard system, independent of the chosen e.Guard level.

Features:

• Suitable for detecting Type B fault currents
• Monitored frequency range: 0 Hz to 100 kHz
• Monitored circuit: max. 690 V (AC) / 1000 V (DC), 400 A
• Robust plastic housing
• Easy installation
• Configuration of various settings and output of differential current values via Ethernet
• 2 configurable alarm relays with potential-free changeover contacts
• Operating voltage via PoE (Power over Ethernet) or 24 V DC direct connection
• Mounting type: Attachment is done on load-bearing surfaces or a mounting plate using the available screw points

Applications: The monitoring device is suitable for use in power supplies of purpose-built and industrial facilities with TN-S, TN-C-S networks, IT networks, and DC networks, for example, in server rooms of data centers, in laboratories, in the automotive industry, and in connection with PV and UPS systems with transformerless inverters, air conditioning units, frequency converters, switch-mode power supplies, high-frequency current converters, printing machines, and packaging machines.

Suitable for monitoring DC circuits and systems where electronic operating equipment can cause smooth DC fault currents or fault currents with frequencies other than 50 Hz.

Notes: Individual configuration is done via the e.Guard software. Name change: from DCTR B-X Hz 035 PoE and DCTR B-X Hz 070 PoE to e.Guard RCM B 035 and e.Guard RCM B 070. The products are now available under their known article number or the new name.
