At 40 °C it carries 50 A continuous; the interrupting rating hits 52.5 kA at 240 V AC and still holds 32 kA at 415 V, so it handles high-fault commercial and light industrial service without cascading upstream.
Above that it drops to 49 A at 55 °C and 45 A at 70 °C, so a panel running near the upper ambient limit loses about 10 % headroom. Breaking capacity is voltage-dependent: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500 V or 690 V.
The 3VA1050-2ED32-0AF0 measures 76.2 mm wide, 130 mm high, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling.
