Circuit breaker 3VA6 UL Frame 250 switching capacity class H 65kA @ 480V 3-pole, system protection ETU856, LSI, In=250A overload protection Ir=100A...250A short-circuit protection Isd=0.6..10x In, Ii=1.5..10x In N-conductor protection optionally with external current transformer, up to 160% ground fault alarm message via EFB300 or COM without connection 3VA6 molded case circuit breaker with ETU 8-series for system protection, 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 through safe shutdown in the event of overload and short circuit. The 3VA UL sets standards in terms of flexibility and modular accessories. 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 implemented worldwide for systems. 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. Available as a 3- and 4-pole version. 4. Four switching capacity classes from 55 kA to 150 kA at 480 V. 5. Depending on the size: Rated current 40 A.600 A. 6. Installation in fixed installation, plug-in technology, withdrawable technology possible. 7. The series has an electronic overcurrent release. 8. Has an integrated display for measuring value display. 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 a wide range of functions. www.siemens.de/3VA.
