Rated 63 A continuous at 40 °C (derated to 58 A at 70 °C), it breaks up to 75.6 kA at 240 V and 52.5 kA at 415 V, which covers most industrial service-entrance and sub-feed applications. Rated insulation voltage is 800 V, and the breaking capacity at 690 V is still 11.9 kA — usable on 480/600 V class systems where fault current stays under that threshold. The shunt trip (STL) auxiliary release is built in, so remote tripping for emergency-stop or interlock circuits is wired at the factory, not added later. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — standard 3-pole MCCB footprint for a 63 A frame.
At 55 °C it drops to 62 A, at 65 °C to 60 A, and at 70 °C to 58 A. If the panel runs hot (sun-loaded roof, adjacent heat source), the 58 A floor still covers a 60 A feeder with margin.
