The 330 kA at 415 V is the figure that governs most European 400 V distribution panels — it's well above typical transformer fault levels (usually 25–50 kA), so this breaker gives substantial selectivity headroom downstream. At 690 V the 52.5 kA still covers most motor-drive branch circuits, but verify against your transformer impedance if feeding a 690 V bus. ## Ground-fault monitoring and trip functionality Ground-fault monitoring uses summation current formation on L + N conductors — it measures vector sum of phase and neutral currents, so it detects leakage to earth without a separate sensor. Trip indicator is absent, and there is no undervoltage release or voltage trigger. The breaker is a straight thermal-magnetic line-protection device with added ground-fault sensing, not a full electronic trip unit. Maximum power loss is 7.7 W at rated load, which matters for ventilation in sealed enclosures.","metaTitle":"Siemens 3VA2010-8HM46-0AA0 SENTRON MCCB, 100A 4-Pole, 330kA","metaDescription":"Siemens 3VA2010-8HM46-0AA0 SENTRON molded case circuit breaker, 100A continuous, 4-pole, 330kA breaking capacity at 415V.

The key difference is that 3VA2010-8HM46-0AA0 includes ground-fault monitoring via summation current, while 3VA2010-8HL42-0AA0 does not. If the panel wiring already accommodates a neutral conductor pass-through for the ground-fault sensor, it drops in without rewiring; otherwise, a neutral bar connection may be needed."},{"question":"What compliance documentation does Siemens provide for 3VA2010-8HM46-0AA0?","answer":"As a current-production SENTRON MCCB, standard documentation includes IEC/UL certification, CE marking, RoHS and REACH compliance declarations.
