Breaking capacity is the headline spec here: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. Those are high-interrupting ratings for a 100 A frame — this breaker handles fault currents that would vaporize a standard industrial MCCB.
The 3VA2010-8JQ32-0AA0 measures 86 mm deep, 105 mm wide, and 181 mm tall — a 3-pole frame that fits standard MCCB mounting footprints in switchgear and panelboard layouts. Maximum power loss is 7.7 W, which is modest for a 100 A MCCB. In a sealed, non-ventilated enclosure with multiple breakers, that loss figure helps calculate internal temperature rise and whether forced ventilation is needed.
The 100 A continuous rating is flat across the 40–70 °C operating range — no thermal derating curve to manage. That is unusual for an MCCB; most frames lose capacity above 40 °C. Here, the breaker delivers its full 100 A even at 70 °C ambient, which simplifies panel thermal design. This is not a full ground-fault relay, but it provides basic earth-leakage awareness within the breaker itself. Communication function is present, so the breaker can report status and trip events to a higher-level system, though the protocol is not detailed in the basic spec set.
