The Siemens 3RV2711-0KD10 is a SIRIUS-brand circuit breaker in size S00, designed for system protection per UL 489 and CSA C22.2 No. 5. Rated voltage spans 20 to 690 V, covering most low-voltage industrial supplies. The motor rating at 230 V is 0.2 kW — a light load, typical for small pumps or fans on a sub-feed.
Panel fit and wiring constraints
Dimensions are 97 mm deep, 45 mm wide, 144 mm tall. That 0 mm forwards means it can sit flush against a gland plate or enclosure wall without airflow worry — but the 70 mm top/bottom gap is mandatory for arc-quenching and terminal access. Use a Pozidriv size 2 tip or a 5–6 mm diameter screwdriver shaft. Torque to M4 on the main contacts — no special crimp tool needed for the wire range.
Environmental and operating limits
Maximum switching frequency in AC-3 duty is 15 operations per hour — not a cycling application; this is a protection device, not a contactor for frequent starts.
