T connector accessory for: 3VA Communication for 3VA molded-case circuit breakers. The 3VA molded case circuit breaker uses an innovative, modern communication concept. This concept is based on the COM100 or COM800 breaker data server, which can link up to eight molded case circuit breakers to different bus systems. This allows plants to transfer relevant data such as energy and diagnostic information to a higher-level automation system for processing. These accessories are characterized primarily by: 1. The metering function integrated in 8-series ETUs can acquire energy data without requiring additional external transformers. 2. The COM800 breaker data server provides a cost-efficient communication interface for up to 8 3VA2 molded case circuit breakers. 3. Integrated Modbus TCP interface (COM800/COM100). 4. Expansion modules available for the COM800/COM100 breaker data server for connection to PROFINET, PROFIBUS, Modbus RTU. 5. Universal S0 interface for the output of energy pulses. 6. Status and measured values of up to 8 molded case circuit breakers are displayed in the cubicle door using the DSP800.
