24 V module accessory for: 3VA2 100/160/250 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. Key features of these accessory components: 1. Integrated metering function in series 8 ETUs enables energy data acquisition without additional external measuring 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). 3. Expansion modules available for COM800/COM100 breaker data server for connection to PROFINET, PROFIBUS, Modbus RTU. 4. Universal S0 interface for the output of energy pulses. 6. Status and measured values of up to 8 molded-case circuit breakers displayed in the cubicle door with DSP800. &DPMD_ACC602_001_000_1003333&
