The 200 A rating holds flat from 40 °C through 50 °C — no derating needed in a typical 40 °C panel — then steps down to 192 A at 55 °C, 188 A at 60 °C, 184 A at 65 °C, and 180 A at 70 °C. That temperature profile matters when you're packing this into a crowded enclosure; the breaker sheds 8 A per 5 °C rise above 50 °C. Breaking capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. At 415 V — the common European industrial voltage — 121 kA means this breaker handles high-fault scenarios without cascading upstream. It does carry an undervoltage release (UVR) and phase-failure detection. The basic switch is 3VA2220-5MN32-0AA0; the integrated auxiliary trip is 3VA9608-0BB11. Latching endurance is 20 000 operations.
Maximum power loss is 75 W — account for that in the enclosure thermal budget. Phase-failure detection is built in — no separate phase-loss relay needed.
