Product details

Transformer-protection circuit breaker, 100 kA SCCR

The Siemens 3RV2811-0FD10 is a SIRIUS-brand circuit breaker specifically designed for transformer protection, complying with UL 489 and CSA C22.2 No. 5. Rated operational voltage spans 20 to 690 V, covering most global low-voltage industrial supplies. That matters for thermal derating and arc-flash containment in a crowded panel — maintain those gaps to keep the 100 kA rating valid.

No official successor has been issued; the SIRIUS 3RV2 family is the established platform. Check terminal ratings: this unit uses M4 main-contact screws and accepts 1–10 mm² solid/stranded.

Integration notes

Screw terminals accept Pozidriv size 2 or a 5–6 mm diameter screwdriver shaft. No ground-fault or phase-failure detection built in — this is a straightforward magnetic/thermal breaker for transformer primary protection. The 100 kA SCCR holds at 240, 400, 500, and 690 V AC — no voltage-dependent derating on the interrupting capacity within that band.

Frequently asked questions

Will 3RV2811-0FD10 drop into a panel designed for 3RV2011-0AA10?

Both are S00 frame size, 45 mm wide, and mount on 35 mm DIN rail, so the mechanical footprint is identical. However, the 3RV2811-0FD10 is a transformer-protection breaker (UL 489), while the 3RV2011-0AA10 is a standard motor-protective breaker — verify the trip curve and interrupting rating match your application before substitution.
