Those figures are the ultimate short-circuit breaking capacity (Icu) for the respective voltages — high enough to serve as the main breaker in a panel with a large transformer feeding multiple downstream feeders. ## Physical integration Dimensions are 248 mm high, 184 mm wide, and 110 mm deep. The 4-pole footprint matches the standard SENTRON 3VA2 panel cutout; verify the mounting base and busbar spacing against your existing switchboard layout. The ETU350 trip unit is field-adjustable, and the neutral protection setting (OFF / 50% / 100%) is selected via DIP switches on the front.","metaTitle":"Siemens 3VA2325-7HN42-0AA0 SENTRON MCCB, 250 A, 4-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2325-7HN42-0AA0 molded case circuit breaker, 250 A continuous, 4-pole, ETU350 trip unit.
