Its interrupting capacity hits 121 kA at 240 V and still holds 75.6 kA at 415 V — that's serious fault-clearing for high-available-current service entrances or industrial sub-distribution.
Thermal derating curve — the real current rating
At 55 °C it drops to 62 A, at 60 °C to 61 A, at 65 °C to 60 A, and at 70 °C to 58 A. That's a gentle slope — you get nearly full rating in a warm panel. The maximum power loss is 17.3 W, so heat buildup in a tight enclosure is manageable.
Interrupting ratings by voltage
The interrupting ratings step down cleanly: 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.
Built-in accessories and panel fit
That's enough for remote tripping and status feedback without adding external modules. The 70 mm depth × 76.2 mm width × 130 mm height footprint is standard SENTRON 3VA — it drops into the same DIN-rail or screw-mount cutout as other 3VA frames.
