The 3VA1180-4EF32-0AH0: The 80 A rating holds across 40 °C to 50 °C ambient without derating; above that it steps down to 76.8 A at 55 °C and 72 A at 70 °C. For a panel builder, that means the breaker can be loaded to its nameplate in most ventilated enclosures, but a hot corner near the top of a sealed cabinet needs the thermal curve checked. Interrupting capacity at 690 V drops to 11.9 kA, which is typical for a 3-pole MCCB on a 690 V line — the series is optimized for 400–480 V distribution where the high fault currents live.

Frequently asked questions
What is the interrupting capacity of this MCCB at 415 V?
The 3VA1180-4EF32-0AH0 interrupts 75.6 kA at 415 V, which is the typical rating for 400 V distribution panels.
Where can I buy 3VA1180-4EF32-0AH0 and get current pricing?
This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
Will 3VA1180-4EF32-0AH0 drop into a panel specified around 3VA1110-5EE32-0JA0?
Both are 3-pole SENTRON MCCBs in the same 3VA1 series, so the mounting footprint and bus-bar spacing are shared — no rewiring of the panel layout is needed. The difference is in the trip unit and rating; verify the 80 A continuous current and TM240 release match the circuit requirements before substituting.
