EXTERNAL FUNCTION BOX EFB300

external function box EFB300 incl. connecting cable 1.5m 3VA-EFB300 accessory for: 3VA2 3VA communication scalable for every use case. The 3VA2 molded case circuit breaker utilizes an innovative, modern communication concept. This concept is based on the COM800 breaker data server which can link up to eight molded case circuit breakers to different bus systems. The integrated Rogowski coils in the 3VA2 molded-case circuit breakers allow especially accurate recording of the current values. The 3VA Siemens communication accessories are primarily characterized by: 1. Integrated measuring function in ETUs of the 8 series allow the acquisition of energy data without additional external converter. 2. The COM800 data concentrator provides a cost-optimized communication interface for up to eight 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 the output of energy pulses 5. 100 test results can be stored with the TD500 test device. 6. Display of the status and the measured values of up to 8 molded-case circuit breakers in the control cabinet door with the DSP800. http://www.siemens.com/3VA Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, distribution boards as well as switches and sockets for safe and efficient electrical infrastructure in buildings and industry.
