What this MCCB does — and what it doesn't
That 80 A holds flat from 40 °C up to 50 °C, then derates to 76.8 A at 55 °C and 72 A at 70 °C — so if your panel runs hot, you've got the curve to check without guessing. The interrupting ratings climb to 75.6 kA at 240 V and 52.5 kA at 415 V, which covers most industrial service-entrance and feeder applications. The auxiliary contact version ships with 2 HQ switches, and the integrated auxiliary trip order code is 3VA9688-0BL32 if you ever need a spare or replacement.
Panel fit and physical integration
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — that's a 3-pole footprint that drops into a standard SENTRON mounting base without surprises. The 3VA1080-3ED32-0JC0 has no trip indicator on the front, so if you need visual trip status at a glance, you'll rely on the auxiliary contacts or a separate indicator. Latching endurance is rated at 15,000 operations — plenty for a feeder breaker that cycles infrequently.
