Автоматический выключатель 3VA6 UL frame 250 breaking capacity class H 65kA @ 480V 3-pole, line protection ETU850, LSI, In=250A overload protection ir=100A ...250A short circuit protection Isd=0,6..10x In, iI=1,5..10x In neutral protection optional with ext. ct,upto 160% w/o connection 3VA6 molded-case circuit-breaker with 8-fold ETU for system protection, 100% Rated Breaker, UL approval. As an important part of the SENTRON protective components for industrial applications and for infrastructure applications, the 3VA UL molded-case circuit breakers from Siemens provide effective plan and starter protection thanks to a reliable shutdown in the event of an overload or short-circuit. The 3VA UL sets standards in flexibility and the variety of modular accessories available. The "100% rated versions of the 3VA6 molded case circuit breaker can be continuously operated with 100% of the specified rated current. They are tested and certified to this end. In addition, the 3VA UL molded case circuit breaker is also optimally suited to mechanical engineers and switchgear manufacturers who export worldwide. In addition to the IEC Standard, the two series, the 3VA5 and 3VA6, also satisfy the UL Standard. All of the functions can thus be used for plants around the world. This variant of the 3VA molded case circuit breaker is characterized primarily by: 1. Compact design. 2. Available as a variant for system protection. 3. 100% rated breaker. 4. Available as 3 and 4-pole version. 5. Four breaking capacity classes from 55 kA to 150 kA at 480 V. 6. Depending on the size: rated current 40 A...400 A. 7. Installation possible as fixed installation, in plug-in design, in withdrawable design. 8. The series has a solid-state overcurrent release. 9. Has an integrated display for displaying measured values. 10. Integrated measuring function and optional communication connection via Modbus TCP, Modbus RTU, PROFINET and PROFIBUS. 11. Modular and easy-to-fit internal accessories with diverse 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 and efficient electrical infrastructure in buildings and industry.
