External extension module EFB300 including connection cable 1.5m 3VA-EFB300 Accessories for: 3VA2 3VA communication scalable for every application. The 3VA2 molded case circuit breakers offer an innovative and modern communication concept. The basis of this concept is the COM800 data concentrator, which can connect up to eight molded case circuit breakers to various bus systems. The integrated Rogowski coils in the 3VA2 molded case circuit breakers allow particularly precise recording of the current values. The Siemens 3VA communication accessories are characterized above all by: 1. Integrated measuring function in ETUs of the 8 series enable energy data recording without an additional external converter. 2. The COM800 data concentrator offers a cost-optimized communication interface for up to 8 3VA2 molded case circuit breakers. 3. Universal bus interfaces for the data concentrator (PROFINET, PROFIBUS, Modbus RTU, Modbus TCP) COM800/COM100 available. 4. Universal S0 interface for outputting energy pulses 5. Saving of 100 test results with the TD500 test device. 6. Display of the status and measured values of up to 8 molded case circuit breakers in the control cabinet door with the DSP800. www.siemens.de/3VA Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, installation distributors as well as switches and sockets for safe, efficient electrical infrastructure in buildings and industry.
