It's built around the ETU350 electronic trip unit, which gives you adjustable long-time, short-time, and instantaneous protection curves — useful for coordinating downstream feeders without nuisance tripping. Breaking capacity is the headline here: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and still 40 kA at 690 V. That's serious fault-clearing muscle for high-available-fault-current panels — think utility tie points, large transformer secondaries, or industrial mains where the upstream transformer is big enough to deliver a 200 kA bolted fault. Thermal derating is published across the full operating range: 630 A at 40 °C, stepping down to 520 A at 70 °C.
The breaker ships with the basic switch 3VA2463-6HN32-0AA0 and the integrated auxiliary trip 3VA9608-0BB24 as internal components — these are the factory-fitted sub-assemblies, not field-installable accessories.
Maximum power loss is 162 W at rated current — factor that into your enclosure thermal budget if you're packing multiple breakers in a sealed cabinet.
