Circuit breaker 3VA6 UL Frame 150 breaking capacity class M 35kA @ 480V 4-pole, system protection ETU820, LI, In=40A overload protection Ir=16A...40A short-circuit protection Ii=1, 5...12 x In without connection 3VA6 molded case circuit breaker with 8-series ETU for system protection, 100% rated breaker, UL approval. The 3VA UL molded case circuit breakers from Siemens, as an important component of the SENTRON protection components for industrial applications as well as for applications in the infrastructure sector, offer effective system and starter protection by safely switching off in the event of overload and short circuit. The 3VA UL sets standards in flexibility and modular accessory variety. The 100% rated versions of the 3VA6 molded case circuit breaker can be operated continuously with 100% of the specified rated current. They are specially tested and validated for this purpose. The 3VA UL molded case circuit breaker also offers the best conditions for machine and switchgear manufacturers exporting worldwide. In addition to the IEC standard, the two series 3VA5 and 3VA6 also meet the UL standard. All functions can therefore be used and deployed in systems worldwide. This variant of the 3VA molded case circuit breaker is characterized above all by: 1. Compact design. 2. Available as a variant for system protection. 3. 100% rated breaker. 4. Available as a 3- and 4-pole version. 5. Four switching capacity classes from 55 kA ... 150 kA at 480 V. 6. Depending on the size: rated current 40 A...400 A. 7. Can be installed in fixed installation, plug-in technology, or withdrawable technology. 8. The series has an electronic overcurrent release. 9. Has an integrated display for measuring value display. 10. Integrated measuring function and optional communication connection via Modbus TCP, Modbus RTU, PROFINET and PROFIBUS. 11. Modular and easy-to-install internal accessories with a wide range of functions. www.siemens.de/3VA. Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, distribution systems as well as switches and sockets for safe, efficient electrical infrastructure in buildings and industry.
