At 55 °C it drops to 30.72 A, and at 70 °C to 28.8 A. If your enclosure runs hot, the full thermal curve is on record. Breaking capacity at 690 V is 7.5 kA — that's the limit for 690 V line-to-line faults; for DC networks the manual (3VA device manual) gives the derating.
The 3VA1032-3ED32-0HA0 measures 130 mm high × 76.2 mm wide × 70 mm deep. Three-pole block, no auxiliary contact stack. The shunt trip (STL) is factory-fitted — verify control voltage compatibility with your trip circuit. No communication module, no phase-failure detection; this is a straight line-protection breaker.
