Product details

Rated 125 A continuous at 40 °C ambient, it holds that rating through 50 °C before derating starts — 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, 114 A at 70 °C. That thermal curve matters if you're packing this breaker into a hot enclosure. Breaking capacity hits 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. That's enough to clear a high-fault industrial service without upstream coordination headaches.

The TM210 release is fixed thermal-magnetic; you set the magnetic pickup via the rating plug, not a dial.

Frequently asked questions

Where can I buy the 3VA1112-4ED32-0AA0?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or lead-time number is published here.

Will the 3VA1112-4ED32-0AA0 drop into a panel built for the 3VA1110-5ED32-0AA0?

Both are 3-pole SENTRON MCCBs with the same 70 mm depth and 76.2 mm width, so the physical footprint and bus-bar spacing are identical. The difference is the trip unit: the 3VA1112-4ED32-0AA0 carries a TM210 release rated 125 A, while the 3VA1110-5ED32-0AA0 uses a different TM release. If the panel was wired for 125 A, this one drops in without rewiring.
