Three poles, rated 100 A continuously at 40 °C, and it holds that same 100 A rating through 50 °C before derating begins (98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, 91 A at 70 °C). That thermal stability matters when the breaker lives inside a warm motor control center. Breaking capacity is the headline: 220 kA at 240 V AC, 154 kA at 415 V, 121 kA at 440 V. That's high-interrupting — it handles fault currents from large transformers or parallel feeders without cascading upstream. Power loss maxes at 25 W — a number to check for thermal coordination inside a sealed enclosure.
Integrated trip and auxiliary hardware
The basic switch core is order code 3VA11106MH360AA0 — the factory-assembled internal mechanism. The 3-pole width is standard for a 100 A frame — fits existing SENTRON mounting bases and busbar adapters without panel rework if you're swapping from a same-frame 3VA1. The trip indicator is not fitted on this order code — if local code requires a visible trip flag, confirm with the panel builder before installation.
