Smart, all-current-sensitive residual current monitors (type B) reliably detect fault as well as residual currents and report them without switching off the system. The Ethernet interface transmits the measured residual current values via Modbus TCP protocol. The smart residual current monitors are an integral part of the e.Guard system, regardless of the selected e.Guard LEVEL.

suitable for detecting Type B residual currents, monitored frequency range 0 Hz – 100 kHz, Rated voltage of monitored circuit up to 690 V, compact, robust plastic housing, easy mounting, Configuration of various settings and sending of residual current values over Ethernet, 2 configurable alarm relays with potential-free changeover contacts, Operating voltage from PoE (Power over Ethernet) or direct 24 V DC connection

The devices are mounted on stable substrata using the supplied mounting brackets.

The monitoring device is suitable for use in power supplied to purpose-built buildings and industrial facilities with TN-S, TN-C-S networks, IT networks and direct current networks, such as in server rooms for data centres, laboratories, in the automotive industry and in conjunction with photovoltaic and UPS systems with frequency converters without transformers, air conditioning systems, frequency converters, switching power supplies, high-frequency converters, printing machines and packaging machines. , Suitable for monitoring DC circuits and systems in which electronic equipment may generate smooth DC residual currents or residual currents with frequencies not equal to 50 Hz.

Custom configuration is from the DCTR Manager software.
