It breaks 6 kA per IEC 60898 and 5 kA per UL 1077 / CSA C22.2 No. 235, so it covers both IEC and North American panel specs from the same bin. That's one SKU covering two approval regimes — saves a cross-reference lookup when the BOM crosses borders.
At 32 A it handles a 7.5 kW three-phase heater bank or a lighting subpanel comfortably. The UL 1077 supplementary-protector rating of 5 kA tells you it's listed as a branch-circuit protector in North America, not a main — keep that straight when the panel schedule calls for a UL 489 listed main breaker. Temperature derating is baked in: 32 A at 35 °C, 30.5 A at 40 °C, 29.7 A at 45 °C, 28.9 A at 50 °C, 28.06 A at 55 °C. If the panel ambient runs at 50 °C, you're effectively holding a 28.9 A breaker — size the upstream conductor for that, not the 32 A nameplate. The IP20 rating applies with conductors connected; the breaker itself is finger-safe, but the busbar area needs enclosure protection.
Mounting position any orientation, supply feed from either end. Sealable with a lead seal or sticker for tamper-evident applications. Halogen-free and silicon-free construction — no corrosive off-gassing in a sealed enclosure near sensitive electronics.
