Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — that's the SCCR headroom for high-fault panels without cascading upstream.
Thermal derating — the real ampacity curve
Above that, it starts pulling back: 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C. If your panel ambient sits at 60 °C, you're losing about 2 A — enough to matter on a fully loaded feeder.
That's a standard SENTRON 3VA frame width — drops into a DIN-rail or panel-mount footprint without surprises. The 15 000 mechanical endurance cycles tell you it's built for a fixed installation, not frequent switching.
