What this MCCB does on the line side
It's a line-protection device — meaning it sits upstream protecting a feeder or distribution bus, not a motor branch. The interrupting capacity scales with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. For a 400 V panel, that 52.5 kA rating clears most utility-fault scenarios without cascading upstream. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — the width is a standard 3-pole MCCB footprint, so it drops into existing SENTRON or 3VA panel layouts without re-drilling the gland plate.
Above that it derates: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C. The storage limit governs shipping and spares on the shelf, not running conditions.
The shunt trip is ordered separately as 3VA9688-0BL30 — it's a voltage-trigger coil that lets a PLC or E-stop pushbutton open the breaker. It's a basic line-protection MCCB with remote-trip capability; if you need UVR or ground-fault, step to a different 3VA variant.
