The interrupting ratings are the headline: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 5 kA at 690 V. The thermal derating curve is flat from 40 °C to 50 °C at full 100 A, then steps down: 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C. The maximum power loss is 12.5 W, which is modest for a 100 A frame; helps keep internal cabinet temperature rise manageable.
Auxiliary and undervoltage release fit
The UVR is factory-fitted as part of the basic switch assembly (3VA2110-6HL32-0AA0) and the auxiliary trip module is order code 3VA9608-0BB25. If you're replacing an existing MCCB in a panel that uses UVR for emergency-stop or undervoltage protection, this variant drops in without rewiring the shunt trip circuit. That's a standard 3VA2 frame footprint — same width as the 3VA1 series, so it fits the same DIN-rail or screw-mount baseplates.
