Breaking capacity across voltage levels
The 3VA2110-7MS32-0AF0: This MCCB delivers 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V. Those numbers define the maximum fault current the breaker can safely interrupt at each voltage — critical for selectivity studies and SCCR compliance in a distribution panel.
Thermal derating and power loss
The breaker holds its full 100 A rating up to 50 °C ambient. Above that, it derates linearly: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. Maximum power loss is 75 W. Operating range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
Dimensions and auxiliary contacts
Footprint is 105 mm wide by 181 mm tall by 86 mm deep — standard for a 3-pole 3VA2 frame. It ships with one auxiliary switch and one trip alarm switch (HQ type), plus the integrated auxiliary trip order code 3VA9608-0BB24. The supplied basic switch is 3VA2110-7MS32-0AA0. No undervoltage release, no ground fault monitoring, no communication function.
