Product details

Integrator note — SIRIUS 3RV2811-0BD10

The Siemens 3RV2811-0BD10 is a SIRIUS circuit breaker sized S00, designed specifically for transformer protection and listed under UL 489 / CSA C22.2 No.5. The 45 mm width and 97 mm depth fit a standard 45 mm-wide module slot; plan for 70 mm clearance above and below, 30 mm at the sides, zero forward or backward clearance needed. Rated voltage span covers 20 to 690 V.

Panel integration — clearance and wiring

Use a Pozidriv size 2 screwdriver with a 5 to 6 mm shaft diameter. Main contact screws are M4. Ground fault and phase failure detection are not built-in — the breaker is a straight thermal-magnetic device for transformer protection. Clearance: 70 mm above and below the breaker, 30 mm at the sides, zero forward or backward. This keeps arc-flash venting and thermal dissipation within manufacturer limits.

Frequently asked questions

Will 3RV2811-0BD10 drop into a panel that was specified around 3RV2011-0AA10 without rewiring?

Yes. Both breakers share the same S00 frame, 45 mm width, 35 mm DIN rail mounting, and M4 screw terminals accepting 1 to 10 mm² conductors. The power connections and DIN rail footprint are identical.

What compliance documentation does this brand provide for 3RV2811-0BD10?

The breaker is designed for transformer protection per UL 489 and CSA C22.2 No.5. Standard Siemens SIRIUS documentation includes RoHS and REACH declarations; the UL/CSA listing is the primary safety certification.
