Residual current transformers, 4–20 mA interface, Type B, 35 mm

Residual current monitors (RCM) reliably detect and report fault and differential currents without switching off the system. They are used wherever the system cannot be switched off, or this is not desired. Residual current monitors from series DCTR have an integrated bushing transformer offering compact design and easy installation. The device continuously detects the height of the current differential current (residual current). This value is reproduced proportionally as a 4-20-mA signal. If the fixed response threshold is exceeded, a potential-free changeover contact activates. A multicoloured LED signals this status (red) or that the device is ready (green). Residual current monitors with characteristic B detect pulsating and smooth DC residual currents as well as AC residual currents up to 100 kHz. These device variants work with a fixed residual operating current value of 0.3 A for the alarm relay. The DCTR outputs the measured nominal response residual current proportionally as a 4-20 mA signal.

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, Output of the nominal response residual current over 4-20 mA interface, Alarm relay with potential-free changeover contacts, Operating voltage 24 V DC

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.
