Dimensions are 86 mm depth, 140 mm width, and 181 mm height — fits standard Siemens SENTRON mounting footprints. Verify panel cutout and busbar spacing against these before committing the BOM line. Built-in ground-fault monitoring via summation current formation on L+N conductor means it detects leakage to ground without an external GFCI module — saves panel space and wiring on circuits that require ground-fault protection. Communication function is present, enabling integration with plant monitoring systems for remote trip indication and load profiling — useful for predictive maintenance on critical feeders.","metaTitle":"Siemens 3VA2025-7KQ42-0AA0 SENTRON MCCB, 25 A, 4-Pole, Line","metaDescription":"Siemens SENTRON 3VA2025-7KQ42-0AA0 molded case circuit breaker, 25 A continuous, 4-pole, line protection.
