Interrupting capacity drops with system voltage: 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 11.9 kA at 690 V. Thermal current holds flat at 320 A from 40 °C through 50 °C, then derates to 313 A at 55 °C and 292 A at 70 °C. In a warm enclosure with multiple devices, use the 70 °C row for conservative sizing.
Footprint is 138 mm wide by 248 mm tall by 110 mm deep — a standard SENTRON 3VA form factor that fits existing 3VA panel cutouts and busbar arrangements. The 110 mm depth leaves room behind a 200 mm deep enclosure for wiring and auxiliary wiring channels.
