What it is and what it does
The Siemens 3RV2011-0HA10-ZW97 is a SIRIUS motor protection circuit breaker, size S00, Trip Class 10. Phase failure detection is built in.
Key ratings and what they mean for fit
Breaking capacity hits 100 kA at 240 V, 400 V, 500 V, and 690 V AC — that's industrial-grade fault clearance, meaning it can sit upstream of a motor starter without needing a separate fuse for SCCR compliance in most panel builds. Rated operational voltage spans 20 to 690 V, so it covers 400 V and 480 V common bus voltages. The 45 mm width and 97 mm depth fit the S00 footprint; screw terminals accept 2x (0.75 to 2.5 mm²) solid or stranded, or 2x 4 mm² — typical for motor branch circuits up to that cross-section. Mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, any position. Clearances: 50 mm above and below, 30 mm to the side, zero forward or backward — tight panel layouts can squeeze it in. Ambient operating range -20 to +60 °C; storage and transport -50 to +80 °C.
Panel integration note
Snap-on DIN rail mounting (35 mm per DIN EN 60715) with screw-terminal main contacts (M3). The 45 mm width is one standard module — no special adapter needed. Clearance above and below is 50 mm; side clearance 30 mm. Zero forward or backward clearance means it can sit flush against a back panel or enclosure wall.
