SIRIUS 3RV2011-0EA40 — Motor Protection Circuit Breaker, Size S00
The Siemens 3RV2011-0EA40 is a SIRIUS motor protection circuit breaker in size S00, designed to protect motors against overload and short-circuit. It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, with a compact 45 mm width that saves panel space. Trip Class 10 means it trips within 10 seconds at 7.2× the thermal setting — standard for general-purpose motor starting on pumps, fans, and conveyors where the inrush doesn't demand a slower class.
Breaking Capacity & Selectivity
Rated 100 kA at 400 V AC and at 690 V AC, this breaker handles high fault currents without upstream fuses in most panel designs — useful when coordinating with a transformer or a main breaker that can't clear a bolted fault alone. Phase failure detection is built in, so a lost leg on the line side trips the breaker and keeps the motor from single-phasing.
Mounting & Panel Fit
Mounting position is any. The 45 mm width and 97 mm depth make it a direct fit in standard S00-size slots. Clearance: 50 mm upwards, 50 mm downwards, 30 mm to the side — no extra space needed front or back. Main circuit connections use ring cable lugs; screwdriver shaft diameter 5–6 mm, tip size 2 / Pozidriv 2.
