It carries a 75.6 kA interrupting capacity at 240 V, derating to 52.5 kA at 415 V and 32 kA at 440 V — the SCCR figures you need for fault-current coordination studies.
Rated 80 A continuous at 40 °C, the 3VA1180-3EF32-0JH0 holds that figure through 50 °C before starting to derate — 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. That's a shallow derating curve, so in a warm panel the breaker still delivers near its nameplate. Maximum power loss is 19.2 W.
Width 76.2 mm, height 130 mm, depth 70 mm — standard 3-pole MCCB footprint for a 3VA frame.
