Rated 63 A continuous across the full 40–70 °C ambient range, it holds its 63 A trip rating without derating in warm enclosures — a useful edge when the panel sits near a heat source or inside a non-climate-controlled cabinet. The interrupting capacity climbs to 242 kA at 240 V, drops to 187 kA at 415/440 V, and holds 121 kA at 500 V. At 690 V it still clears 3.7 kA — enough for most industrial line-side faults, but note the steep fall-off above 500 V if your system runs at 690 V.
The auxiliary switch pack (2 aux + 1 trip alarm HQ) is factory-integrated, so no extra wiring cavity needed for add-on modules.
