Breaking capacity is the headline here: 187 kA at 240 VAC, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V. The 3 kA at 690 V is a reminder that this is a 600 V class breaker; at 690 V you're at the edge of its rating and need to check the application. That's unusual — most MCCBs start to lose capacity above 40 °C. Means you can pack it into a warm enclosure or mount it next to other heat sources and still get the full rating. ## Integration and fit It's a panel-mount unit, not a plug-in base; you bolt the line and load lugs directly. The 105 mm width fits the typical 3-pole MCCB cutout in a distribution panel. Power loss is 13.5 W maximum at rated current. That's low enough that ventilation in a typical panel is adequate, but worth checking if you're stacking multiple breakers in a sealed enclosure.","metaTitle":"Siemens 3VA2010-5JQ32-0AH0 SENTRON MCCB, 100 A, 3-Pole, 187","metaDescription":"Siemens 3VA2010-5JQ32-0AH0 SENTRON molded case circuit breaker, 100 A rated, 3-pole, 187 kA breaking capacity at 240 VAC.
