Rated 25 A continuous at 40 °C, it holds that rating through 50 °C and derates to 23 A at 70 °C — a thermal curve that suits panel environments where ambient heat builds near the top of the enclosure. Interrupting capacity is 52.5 kA at 240 V AC and 7.5 kA at 415 V AC — the 240 V figure covers common North American panelboard fault levels, while the 415 V rating handles European 400 V distribution. The 1-pole body is 25.4 mm wide, fitting a single module on a DIN rail; depth is 70 mm, height 130 mm.
