If your panel ambient runs hotter, the breaker derates linearly: 612 A at 45 °C, 593 A at 50 °C, all the way down to 520 A at 70 °C. That derating curve is the spec that decides whether this breaker holds in a tight, hot enclosure or trips on a warm day. Adjustable thermal-magnetic trip range spans 945 A to 5 670 A. Breaking capacity varies sharply with system voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V. At 240 V, it's a monster; at 415 V, it handles any typical panel fault. This is a line-protection design, meaning it's optimized for cable and busbar protection in main or branch feeders, not motor protection with overload class. The undervoltage release (UVR) is built in — if your control voltage drops, the breaker opens.
Dimensions: 248 mm tall, 138 mm wide, 110 mm deep (9.76 in, 5.43 in, 4.33 in). Power loss is 164.5 W maximum at full load. In a sealed panel with multiple breakers, that heat adds up and drives derating.
The base switch variant is 3VA2463-6HL32-0AA0 — the -0DA0 suffix indicates the undervoltage release is fitted. If you need the same breaker without the UVR, the -0AA0 is the direct alternative. No rewiring needed for the swap; just the release module differs.
