The breaking capacity is the headline here: 440 kA at 415 V AC and still 187 kA at 690 V AC. The ETU330 electronic trip unit gives you adjustable N-conductor protection (OFF, 50%, 100%) and a trip indicator, so you get selectivity coordination downstream without sacrificing fault clearance speed. ## Integration and mounting reality The 3VA2110-0HM46-0AA0 measures 181 mm high, 140 mm wide, and 86 mm deep. The IP40 front protection means the operator interface is splash-resistant but not washdown-rated; keep it indoors or behind a sealed panel door in dusty environments. Power loss is 7.7 W maximum at rated load. That's low enough to ignore for thermal budgeting in a multi-breaker panel, but if you're packing 20 of these in a single enclosure, you still want to account for the cumulative heat — roughly 154 W total, which a standard ventilation grill handles.","metaTitle":"Siemens 3VA2110-0HM46-0AA0 SENTRON MCCB, 100 A, 4-Pole, 440","metaDescription":"Siemens 3VA2110-0HM46-0AA0 SENTRON molded case circuit breaker, 100 A continuous, 4-pole, ETU330 trip unit.
