It carries a continuous current rating of 80 A at 40 °C, with minimal derating up to 50 °C (still 80 A), then dropping to 78 A at 55 °C and 74 A at 70 °C — useful to know if your panel runs hot. The 3-pole unit delivers a short-circuit breaking capacity of 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V, so it handles high-fault scenarios common in industrial mains distribution.
At 415 V it still interrupts 75.6 kA, and at 440 V it handles 52.5 kA — both figures that cover most industrial secondary distribution faults. At 500 V and 690 V the rating drops to 11.9 kA, which is still adequate for many motor control center applications but not for high-fault 690 V buswork.
The two auxiliary switches provide status feedback (open/closed) to a PLC or indication lamp without needing additional add-on modules.
The 3-pole width (76.2 mm) is standard for this frame size — it fits the usual DIN-rail or panel-mount footprint for SENTRON 3VA breakers. No communication function or ground-fault monitoring is built in; this is a straight line-protection device with undervoltage release.
