When your panel can see more than 55 kA, the 3VA2063-6JP32-0AA0 delivers. It switches off 85 kA at 415 V – enough for main incomer and bus‑coupler duty. ETU550 LSI protection lets you dial in coordination perfectly, and the screw‑flat connections (nut keeper) guarantee low‑resistance terminations even under heavy vibration.
