Connection cable for N-CT-3VA Accessory for: external current transformer communication for 3VA molded case circuit breakers. 3VA molded case circuit breakers offer an innovative and modern communication concept. The basis of this concept is the COM100 or COM800 data concentrator, which can connect one or up to eight molded case circuit breakers to different bus systems. This means that system-relevant data such as energy data and diagnostic data can be transmitted to a higher-level automation system and processed. These accessory components are characterized primarily by: 1. Integrated measuring function in ETUs of the 8 series enable energy data to be recorded without an additional external measuring transformer. 2. The COM800 data concentrator offers a cost-optimized communication interface for up to 8 3VA2 molded case circuit breakers. 3. Integrated Modbus TCP interface (COM800/COM100). 3. Expansion modules for the data concentrator COM800/COM100 available for connection to PROFINET, PROFIBUS, Modbus RTU. 4. Universal S0 interface for outputting energy pulses. 6. Display of the status and measured values of up to 8 molded case circuit breakers in the control cabinet door using DSP800. www.siemens.de/3VA.
