It carries a 52.5 kA interrupting capacity at 240 V AC and 7.5 kA at 415 V AC — the 240 V figure is the one that governs most North American panel schedules. At 25.4 mm wide on a 70 mm depth, it fits a standard DIN-rail footprint; the 130 mm height leaves headroom for auxiliary modules above it in the enclosure.
Above that it steps down: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, 74 A at 70 °C. Maximum power loss is 6.4 W, negligible for most DIN-rail layouts but worth a glance if the breaker shares a small gland plate with other heat sources.
Integration notes
IP40 on the front face — suitable for dry indoor panels, not washdown zones. The 500 V rated insulation voltage covers 480 V delta systems with margin. Width of 25.4 mm (1 inch) means it occupies one standard pole position on the DIN rail; plan your fill factor accordingly.
