Its interrupting capacity hits 121 kA at 240 VAC and 75.6 kA at 415 VAC — figures that tell you it handles high-fault utility feeds without cascading upstream.
Rated current holds at 32 A from 40 °C through 50 °C, then derates to 31 A at 55 °C and 30 A at 70 °C — so in a warm panel you still get nearly full ampacity. Breaking capacity across the voltage range: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V.
That's a standard MCCB envelope — it fits existing SENTRON mounting plates and busbar systems without re-drilling.
