Ground-fault monitoring is built in via summation current formation on the L + N conductors, which means it can detect leakage without needing an external GFCI module — useful on distribution panels feeding sensitive loads or wet-area circuits. That 140 mm width for a 4-pole MCCB is standard for the SENTRON 3VA frame — it occupies the same footprint as other 63 A 4-pole units in the series, so a panel laid out for a 3VA2063-8JQ42-0AA0 will accept this breaker without re-drilling the mounting plate or re-routing the bus bars.","metaTitle":"Siemens 3VA2063-7HM42-0AA0 SENTRON MCCB, 63A, 4-Pole, 330kA","metaDescription":"Siemens SENTRON 3VA2063-7HM42-0AA0 molded case circuit breaker, 63A continuous, 4-pole, 330kA breaking at 240V.
