Rated current is 32 A across the 40 °C to 50 °C ambient range, derating to 30 A at 70 °C — so it holds full rating in a warm panel but give it breathing room if the enclosure runs hot. Breaking capacity is the headline here: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and still 17 kA at 500 V and 690 V. That means it handles high fault currents without cascading upstream — critical for main or feeder breakers in high-capacity distribution.
Width is important — 76.2 mm is three 25.4 mm pole pitches, so it occupies standard MCCB footprint on a DIN rail. Depth at 70 mm clears most shallow enclosures. Trip indicator is also absent; fault diagnosis relies on the auxiliary switch state or visual inspection.
