Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V, so it can safely clear very high fault currents typical near large transformers or in high-capacity distribution panels.
Temperature derating and panel fit
At 55 °C it's 15.36 A, at 60 °C it's 15.04 A, at 65 °C it's 14.72 A, and at 70 °C it's 14.4 A. If your panel runs hot, plan for that ~10 % drop at the top end. The 76.2 mm width (about 3 inches) is common for 3-pole frames in this class.
Auxiliary and trip options
The integrated auxiliary trip uses order code 3VA9688-0BL30 — that's the shunt trip coil you'd order separately if you need remote tripping from an E-stop or safety relay.
