It is designed for line protection duty — meaning it protects feeders and distribution branches, not motor loads directly. The interrupting capacity hits 330 kA at 240 VAC and 242 kA at 415 VAC, so it handles high-fault-current points like main switchboards or large distribution panels.
Above that it derates: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C.
Three-pole form factor fits Siemens SENTRON panelboards and most DIN-rail adapter plates for third-party enclosures.
For selective coordination downstream, pair it with SENTRON 3VA1 or 3VA2 series breakers rated below 250 A — the manufacturer's selectivity tables (available in the SENTRON planning guide) give the maximum let-through for each combination. The line-protection design curve (not motor-protection) means it trips faster on short-circuit than a motor-circuit protector would, which improves coordination with downstream feeders.
