Rated 500 A continuously at 40 °C ambient, it holds that rating all the way to 50 °C, then derates slightly to 495 A at 55 °C and 480 A at 70 °C — useful to know if the breaker sits inside a warm panel near other heat sources. Interrupting capacity is 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V — that 187 kA figure at 240 V means it can safely clear a massive fault on a low-voltage distribution bus without rupturing.
Footprint is 138 mm wide by 248 mm tall by 110 mm deep — the 138 mm width is a standard 3-pole MCCB form factor that drops into most panel-mount cutouts without adapter plates. Power loss is 99 W maximum at rated load — factor that into your enclosure thermal calculation if the panel is sealed or has limited ventilation.
