It's designed to handle the big feeder circuits — main switchboards, large motor control centers, or transformer secondaries — where you need high interrupting capacity and selective coordination with downstream breakers. The interrupting ratings tell the story: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 9 kA at 690 V. The continuous current derates as the ambient climbs: 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C.
The 110 mm depth is worth checking against your gland plate clearance and door swing; it's not a shallow breaker. No communication function onboard, no voltage trigger, no ground-fault monitoring version — this is a straight line-protection breaker, not a multifunction power monitor. The basic switch variant is 3VA2463-7HL32-0AA0 if you're cross-referencing a panel that started with that base model.
