Circuit breaker 3VA6 UL Frame 400, switching capacity class M, 35 kA at 480 V, 3-pole, system protection ETU550, LSI, In=250 A overload protection, 100 % rated Ir=100 A...250 A, short-circuit protection Isd=0.6..10x In, Ii=1.5..12x In, N conductor protection optional with external current transformer, up to 160 % without connection. Compact circuit breaker 3VA6 with 5-er ETU for system protection, 100 % rated breaker, UL approval. The 3VA UL compact circuit breakers from Siemens are an essential part of the SENTRON protection components for industrial applications as well as for infrastructure applications. They provide effective system and starter protection through safe disconnection in overload and short-circuit situations. The 3VA UL sets standards in flexibility and modular accessory variety. The 100 % rated versions of the 3VA6 compact circuit breaker can be operated continuously at 100 % of the specified rated current and are specifically tested and certified for this purpose. Additionally, the 3VA UL compact circuit breaker offers the best conditions for globally exporting machines and switchgear manufacturers. Besides the IEC standard, the two series 3VA5 and 3VA6 also meet the UL standard. All functionalities can thus be used worldwide for systems. This variant of the 3VA compact circuit breaker is characterized mainly by: 1. Compact design. 2. Available as a variant for system protection. 3. 100 % rated breaker. 4. Available in 3- and 4-pole versions. 5. Four switching capacity classes from 35 kA to 150 kA at 480 V. 6. Depending on the frame size: rated current 40 A to 400 A. 7. Mounting in fixed installation, plug-in technology, and slide-in technology possible. 8. The series features an electronic overload relay. 9. Equipped with an integrated display for measurement value indication. 10. Optional communication interface via Modbus TCP, Modbus RTU, PROFINET, and PROFIBUS. 11. Modular and easy-to-install internal accessories with diverse functions.
