It carries an interrupting capacity of 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, then 79 kA at 500 V, and 5.1 kA at 690 V — so it handles high available fault current at typical distribution voltages without needing an upstream current-limiting fuse.
Thermal derating and endurance
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. Mechanical endurance is 20 000 operations — that's the latching endurance, not the electrical endurance under load. For a main breaker seeing a few cycles per day, that's a decade-plus of service.
The basic switch assembly carries order code 3VA2225-5HN32-0AA0; the integrated auxiliary trip is 3VA9688-0BL33. No communication module, so it's a standalone breaker for hardwired control circuits.
