Circuit breaker 3VA6 UL frame 250 breaking capacity class M 35kA @ 480V 3-pole, line protection ETU860, LSIG, In=250A overload protection, 100% rated Ir=100A...250A Short-circuit protection Isd=0.6..10x In, Ii=1.5..10x In N conductor protection optionally with external CT, up to 160% Ground-fault protection Ig=0.2...1 x In, tg=0.05-0.8s without 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.
