It's designed for 50 Hz systems and carries a 460 V insulation voltage rating. This is the current-production variant, so it's the one you want for a new BOM line or a panel build that needs a clean lifecycle status.
The 63 A AC-rated current is the continuous load it can carry under normal conditions — sized for a sub-main or feeder circuit, not a final branch. The 30 mA trip threshold is standard for personnel protection (shock/arc-flash mitigation) per IEC 60364. AC-type means it detects sinusoidal residual currents only; if your load has pulsed DC (VFDs, UPS, EV chargers), you'd need an A or B type instead. Instantaneous design means no intentional time delay — it trips within a cycle, which is correct for shock protection but may cause nuisance tripping on loads with high inrush leakage (e.g., long cable runs, surge suppressors).
Mounts on a DIN rail (REG fastening method) in any position. Depth is 77 mm, installation depth 70 mm — standard for a 3-module RCD. Terminal position is top or bottom, which gives flexibility in busbar routing. Not sealable, so no lockout/tagout provision on the device itself. Derating curve is published: at 40 °C it carries 58.6 A, at 50 °C 56.7 A, at 60 °C 53.55 A, and at 70 °C 50.4 A.
