That 220 kA figure at 240 V means it handles very high available fault currents typical on the secondary of large step-down transformers or in high-capacity busway feeds; the 154 kA at 415 V and 121 kA at 440 V still cover most industrial service-entrance and sub-distribution scenarios. At 500 V and 690 V the rating drops to 17 kA, so if the line side is a 480 V or 600 V class system, verify the available fault current is under that threshold.
Ratings that drive the fit
The 80 A rating holds flat from 40 °C to 50 °C, then derates to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C — useful if the breaker lives in a hot enclosure or next to other heat sources. A shunt trip (STL) is built in for remote tripping.
Dimensions: 130 mm high, 76.2 mm wide (3 in), 70 mm deep (2.76 in).
Compliance documentation
As a Siemens SENTRON MCCB, the 3VA1180-6EF36-0JH0 carries the usual compliance documentation: CE marking for the European market, UL/CSA listings for North America, and RoHS/REACH declarations. The exact certification numbers are on the nameplate and in the manufacturer's declaration pack available on request.
