Siemens Digital Industry Short-Circuit/Earth Fault Indicator 6MD2321-1AA00-1AA0. Manufacturer: Siemens Digital Industry. Designation: Resistive Short-Circuit/Earth Fault Indicator, Modbus RTU. Type: 6MD2321-1AA00-1AA0.

The short-circuit and earth fault indicator with directional indication measures voltages via a resistive voltage divider in accordance with IEC 61869-11 and IEC 60044-7, conventional voltage transformers, or 230 V for low-voltage applications. It is designed for low-power current sensors according to IEC 61869-10 and IEC 60044-8 and features 1 digital input and 2 digital outputs. The measurement and calculation of values U, I, P, Q, S, f, cos phi, and energy counting values are performed via Modbus RTU communication. The power supply is DC 24-250 V/AC 230 V.

The digital short-circuit indicator with measurement function is designed for medium-voltage switchgear. The key to continuous improvement in power supply is the precise knowledge of the relevant conditions of the local energy supply network.

The SICAM FCM (Feeder Condition Monitor) is a short-circuit and earth fault indicator with directional indication that operates with protection algorithms and small signal transformer technology according to IEC 60044-8 / IEC 61869-10. Alternatively, the SICAM FCM can also be connected with a capacitive voltage tap to achieve cost-effective directional fault detection in the cable network.

Additionally, there is the possibility to provide current measurement values via the integrated Modbus RTU interface, ensuring an accurate assessment of the distribution network. The SICAM FCM also excels as a cost-effective power meter in the low-voltage network. With its low profile, it is optimized for installation in low-voltage switchgear. EAN: 4025515640288.
