What this 3VA1110-6EF36-0AF0 brings to the panel
The real story here is the interrupting capacity: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and still 17 kA at 690 V. That kind of fault-clearing muscle at the lower voltages makes this breaker a solid choice for high-fault-current points in the network, like a main or a large feeder, where you need selectivity without cascading upstream. At 100 A it holds that rating from 40 °C right up through 50 °C, then starts a gentle derating curve — 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C.
