The 3VA2063-5JQ32-0AA0 is a 3-pole molded case circuit breaker from the Siemens SENTRON 3VA2 series, integrating the advanced ETU560 LSIG electronic trip unit. It provides comprehensive line protection with adjustable overload (L), short-time short-circuit (S), instantaneous short-circuit (I), and switchable ground-fault (G) protection. The adjustable neutral conductor protection (OFF or up to 160% of In) can be realized via an optional external current transformer, offering exceptional flexibility for diverse industrial applications.

Key Features & Technology
