At higher panel temperatures the current must be derated: 15.04 A at 40 °C, 14.56 A at 45 °C, 13.92 A at 50 °C, and 12.96 A at 55 °C. If your panel runs hot, size the load accordingly or you'll nuisance-trip on the thermal element. The 30 mA residual-current trip is the standard for personal protection in most residential and commercial circuits. If your load includes VFDs, UPS gear, or LED drivers that can generate DC fault components, you need a type A or F RCBO instead. The design is instantaneous (no intentional time delay on the residual element), so it trips fast on a ground fault.
Installed depth is 77 mm, overall height 125 mm. Keep it inside a dry enclosure. The part also carries energy limitation class 3, meaning it limits let-through energy well enough to coordinate with downstream equipment in most cases.
