It carries a 187 kA interrupting capacity at 240 V, dropping to 121 kA at 415 V and 440 V, and 75.6 kA at 500 V — figures that tell you it handles high-fault utility feeds or transformer secondaries without cascading upstream.
Above that it steps down: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. The 3-pole construction and 800 V rated insulation voltage suit it for 3-phase systems up to 690 V line-to-line. It includes a communication function, which means it can integrate with a higher-level monitoring or energy-management system — useful for remote trip indication or load shedding in a facility BMS. The 86 mm depth, 105 mm width, and 181 mm height footprint fits standard Siemens SENTRON panel cutouts. If you're swapping an older 3VA1 or 3VL frame, check the mounting hole pattern — the dimensions are close but not identical to earlier generations.
