The 3VA2063-5JQ42-0AA0 is a 4-pole molded case circuit breaker from the Siemens SENTRON 3VA2 series, equipped with the advanced ETU560 LSIG electronic trip unit. It combines overload (L), short-time (S), instantaneous (I) and ground-fault (G) protection with an adjustable neutral conductor protection (OFF or up to 160% of In). The ground-fault function can be switched off, with configurable pickup (Ig: 0.25-1x In) and time delay (tg: 0.05-0.8 s). This model is terminated via a nut keeper kit for secure busbar or lug connections.
