Compact circuit breaker 3VA6 with ETU 8 series for plant protection, UL approval. The Siemens 3VA UL compact circuit breakers are an essential component of the SENTRON protection devices for industrial applications as well as for infrastructure applications. They provide effective plant and starter protection through safe disconnection in the event of overload and short circuit. The 3VA UL sets standards in flexibility and modular accessory variety. Additionally, the 3VA UL compact circuit breaker offers optimal conditions for globally exporting machinery and switchgear manufacturers. In addition to the IEC standard, both series 3VA5 and 3VA6 also meet the UL standard. All functionalities can thus be used worldwide for installations. This variant of the 3VA compact circuit breaker is characterized primarily by: 1. Compact design. 2. Available as a variant for plant protection. 3. Available in 3- and 4-pole versions. 4. Four switching capacity classes from 55 kA to 150 kA at 480 V. 5. Depending on the frame size: rated current 40 A to 600 A. 6. Installation in fixed installation, plug-in technology, or slide-in technology possible. 7. The series features an electronic overload relay. 8. Equipped with an integrated display for measurement value indication. 9. Integrated measuring function and optional communication connection via Modbus TCP, Modbus RTU, PROFINET, and PROFIBUS. 10. Modular and easy-to-install internal accessories with various functions.
