The Siemens SIRIUS 3RV2711-1KD10 is a size S00 circuit breaker designed for system protection per UL 489 and CSA C22.2 No. 5. The interrupting ratings are the headline: 100 kA at 240 V AC, 100 kA at 400 V AC, 42 kA at 500 V AC, and 6 kA at 690 V AC — meaning it can safely clear fault currents up to those levels without upstream damage, critical for high-fault industrial feeders.
Sizing and coordination
The gG fuse coordination limits are 63 A at 400 V, 50 A at 500 V, and 40 A at 690 V — these are the maximum upstream fuse ratings for selective coordination.
Panel integration
The width is a single 45 mm module, so it occupies one slot on a standard DIN-rail panel.
