SIRIUS S00 circuit breaker — 100 kA SCCR, UL 489 system protection
The Siemens 3RV2711-0FD10 is a SIRIUS S00 frame circuit breaker designed for system protection per UL 489 and CSA C22.2 No. 5. It delivers a 100 kA interrupting capacity across the full AC range — 240 V, 400 V, 500 V, and 690 V — so it safely clears faults up to that level without cascading upstream. The rated voltage span runs from 20 V to 690 V, and in AC-3 motor-switching duty the maximum operating voltage is 690 V with a switching rate of 15 operations per hour.
Clearance and coordination
Minimum clearance around the breaker: 70 mm upward, 70 mm downward, 30 mm to the side, and zero forward or backward. These distances matter for thermal dissipation and arc-flash containment in a panel — respect them when laying out the DIN rail. The gG 4 A backup fuse at 690 V is specified for the main circuit protection coordination.
