It carries a 187 kA breaking capacity at 240 V AC, stepping down to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V — so you size it for the available fault current at your service voltage, not just the highest number on the label.
Footprint is 105 mm wide, 181 mm tall, 86 mm deep — a standard SENTRON 3VA form factor that drops into the same mounting holes as the 3VA2 family. The 86 mm depth leaves room for rear-connected busbars in a typical 600 mm deep enclosure.
Current production — no phase-out notice on this order code. The base switch variant is 3VA2225-5HL32-0AA0; this -0AH0 adds the auxiliary switch package and trip alarm.
At 480 V systems (common in North America) the 121 kA at 440 V is the closest published point; for 600 V class gear the 75.6 kA at 500 V applies. Power loss is 48 W maximum at rated current — relevant for thermal coordination in a sealed enclosure, especially if multiple breakers share a compartment.
