At 30 °C ambient the device carries the full 40 A. Derate linearly: 37.6 A at 40 °C, 36.4 A at 45 °C, 34.8 A at 50 °C, 32.4 A at 55 °C and 60 °C, 30.8 A at 65 °C, and 29.2 A at 70 °C. The thermal curve is the governing spec for panel placement — if the RCBO sits next to other heat sources in a crowded enclosure, use the 40 °C or 45 °C row as the design current, not the 30 °C headline.
Touch protection is built in.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commitment.
