Interrupting capacity hits 100 kA at 400 V and 500 V, and 2 kA at 690 V — so it can clear a bolted fault on a high-capacity distribution transformer without needing a current-limiting fuse upstream in most 400 V panels.
Screw-type terminals on the main circuit accept 2×(0.5…1.5 mm²) solid/stranded or 2×(0.75…2.5 mm²) — M3 screws, so a #1 Pozidriv or 5.5 mm nut driver is the tool. No ground-fault detection; if you need that, step up to the 3RV1011‑…‑ZD10 variant. Clearance: 20 mm above and below, 9 mm to the side, zero forward or backward — tight enough for a crowded DIN-rail row.
