Circuit breaker 3VA6 UL Frame 400 breaking capacity class M 35kA @ 480V 4-pole, system protection ETU320, LI, In=250A overload protection Ir=100A...250A short-circuit protection Ii=1, 5...12 x In N-conductor protection adjustable (OFF, 50%, 100%) without connection 3VA6 molded case circuit breaker with ETU 3-series 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 have been specially tested and validated for this purpose. The 3VA UL molded case circuit breaker also offers the best prerequisites 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 functionalities 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. Depending on the size: rated current 40 A ... 400 A. 6. Four switching capacity classes from 35 kA ... 150 kA at 480 V. 7. The series has an electronic overcurrent release. 8. Can be installed in fixed installation, plug-in technology or withdrawable technology. 9. Modular and easy-to-install internal accessories with a wide range of functions. www.siemens.com/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.
