It's a 3-pole unit rated 630 A continuous at 40 °C, with a thermal derating curve that drops to 520 A at 70 °C. That 630 A frame lets you feed a large subpanel or a high-load industrial machine on a single breaker. Breaking capacity is where this part earns its keep: 242 kA at 240 V, 187 kA at 415 V, and still 121 kA at 500 V. If your system fault current is high (big transformer, tight bus), that 242 kA at 240 V saves you from cascading an upstream breaker — the SCCR headroom is real. The adjustable trip range spans 945 A to 5,670 A, so you can dial in the instantaneous pick-up to coordinate with downstream feeders.
Shunt trip and panel fit
That means you can remotely trip the breaker from an E-stop, a safety relay, or a PLC digital output without adding an external undervoltage module. No undervoltage release is fitted, so if you need UVR for a motor starter interlock, you'll add one externally. Footprint: 138 mm wide, 248 mm tall, 110 mm deep. The 162 W maximum power loss means ventilation matters in a sealed enclosure; keep the ambient below 70 °C operating limit.
What to watch
If your maintenance team relies on visual trip indication, factor in a separate indication contact. The voltage trigger is present, meaning the shunt trip responds to a voltage signal; that's typical for remote-trip applications. Also note the basic switch variant 3VA2463-6HL32-0AA0 is the underlying switch core — this order code adds the shunt trip and line-protection trip unit.
