Breaking capacity across voltages
The 3VA1110-4EF32-0HA0: Rated breaking capacity is 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. That covers most industrial distribution panels up to 690 V line-to-line; the 415 V figure is the one to check for European 400 V grids.
Thermal derating and ambient range
Carries full 100 A up to 50 °C ambient; above that it derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. Operating range is -25 °C to 70 °C, storage from -40 °C to 80 °C. If your panel runs hot near the top of the enclosure, factor the derating curve into the branch circuit design.
Mounting and integration
Mounts on a DIN rail or panel — 76.2 mm wide (roughly 3 x 25.2 mm per pole), 130 mm tall, 70 mm deep. IP40 on the front means it's protected against tools and wires >1 mm, but not against water ingress; keep it inside a closed panel. No auxiliary contacts or communication module on this build — the shunt trip is the only auxiliary release.
Lifecycle and sourcing
Listed as current production. No PCN or EOL notice on this order code. Sourced and quoted to order against an RFQ through independent distribution — availability and current pricing confirmed at quote time.
