Interrupting capacity varies sharply by voltage: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, dropping to 3.7 kA at 690 V. The 3.7 kA figure at 690 V is the practical limit — this breaker is not intended for high-fault 690 V motor circuits. The trip current range spans 189 A minimum to 945 A maximum (3x to 15x the 63 A frame), which covers DOL motor starts up to about 30 kW without nuisance tripping.

The 105 mm width (4.13 in) is a standard 3-pole MCCB footprint for a 160 A frame — it occupies the same DIN-rail or panel-mount cutout as other SENTRON 3VA2 devices.
Rated for operation from -25 °C to 70 °C ambient, with no derating required across the full 63 A load range from 40 °C through 70 °C. Maximum power loss is 4 W. Insulation voltage rated at 800 V. The SENTRON series carries UL, CSA, and IEC certifications; compliance documentation (RoHS, REACH) is provided with the unit.
