It carries a rated insulation voltage of 800 V, with interrupting ratings that step down from 187 kA at 240 V to 17 kA at 690 V — meaning it can clear high fault currents at lower voltages while still handling substantial faults at 690 V.
Above that, it derates linearly: 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, and 223 A at 70 °C. Maximum power loss is 57 W at rated current.
The interrupting ratings span the common industrial voltage bands: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. For a 480 V panel, the 75.6 kA at 440 V figure is the closest reference — expect the actual 480 V rating to fall between the 440 V and 500 V values. This gives headroom for most North American and European distribution systems without needing a current-limiting upstream breaker.
The 4-pole width of 140 mm (about 5.5 inches) is standard for this frame size — it occupies four 35 mm DIN spaces if using a DIN-rail adapter, or bolts directly into the panel backplate.
