The interrupting capacity runs 242 kA at 240 V, drops to 187 kA at 415 V and 440 V, then 121 kA at 500 V, and 7.5 kA at 690 V — so the high fault-current headroom is at the lower voltages common in North American distribution, while the 690 V figure keeps it usable on 600 V class systems with moderate fault levels. The basic switch core is order code 3VA2325-6HL32-0AA0, so if you're swapping just the trip unit, that's the reference.
The breaker measures 138 mm wide, 248 mm tall, and 110 mm deep — that's about 5.43 by 9.76 by 4.33 inches.
Thermal and electrical limits
Max power loss is 40 W at rated load — that's the heat you need to vent in a sealed enclosure. The trip indicator is present, and there's no voltage-trigger or communication function on this variant — it's a straight line-protection breaker with undervoltage release.
