Its breaking capacity reaches 440 kA at 240 V AC and 330 kA at 415 V AC, tapering to 52.5 kA at 690 V AC — a curve that tells you this breaker is built for high-fault industrial distribution, not light commercial panels. The thermal derating is mild: it holds 250 A up to 50 °C, then drops to 241 A at 55 °C and 213 A at 70 °C, so you can size it for a warm enclosure without oversizing the frame.
The basic switch core is order code 3VA2225-8HL32-0AA0.
The 86 mm depth is the overall body, not counting handle throw; verify front clearance for the operating mechanism in a shallow enclosure.
