Siemens SIRIUS 3RV1011-1FA10 Motor Starter Protector Switch Used
Safely run and monitor heavy industrial three-phase motor loads without paying full retail distributor expenses. This fully verified, pre-owned Siemens SIRIUS 3RV1011-1FA10 Motor Starter Protector acts as a compact, heavy-duty circuit breaker and thermal overload trip module in a single unit. It provides responsive electromechanical protection against short circuits, phase failures, and continuous electrical overloads within your automated distribution arrays.
| SPECIFICATION / VALUE | DETAILS & BENEFITS |
|---|---|
| Item Condition | USED — Thoroughly inspected second-hand component stock. The non-conductive casing is fully structural with highly legible side schematics, upper and lower wire terminal screw threads are clean, and the rocker switch action breaks with factory-fresh mechanical tightness. Made in Germany. |
| Product Type | 3-Pole (3P) electromechanical thermal-magnetic motor starter protector / circuit breaker. |
| Model / Part Reference | SIRIUS Range / Part Number 3RV1011-1FA10 (Conforms strictly to international standards including IEC/EN 60947-2, IEC/EN 60947-4-1, and ATEX Type II (2) GD / DMT 02 ATEX F001 codes). Certified by UL, CE, CCC, and EAC markings. |
| Thermal Adjustment Range | 3.5 – 5 Amps (3.5-5A adjustable rotary scaling wheel) for calibrated bimetallic overload tracking matched to motor full-load currents. Operating with a Class 10 trip speed curve response. Max backing fuse capacity up to 40A (gL/gG). |
| Short-Circuit Breaking Capacity (Icu) | High performance interrupt capacity: 100 kA at 400V AC and 2 kA at 690V AC system operational voltage parameters. Cat A / AC-3 utilization classification thresholds. |
| Insulation & Voltage Limits | Rated Insulation Voltage (Ui) of 690V AC with a high-capacity Rated Impulse Withstand Voltage (Uimp) capacity of 6 kV. Rated for standard industrial control setups up to 600V maximum under UL/CSA rules. |
| Wiring & Integration | Compact DIN-rail mountable layout footprint. Terminal blocks accommodate solid or stranded multi-wire tracks from 0.5 to 2.5 mm² (AWG 18 to 14) calibrated to a recommended tightening torque of 0.8 to 1.2 Nm (7 to 10.3 lb-in). |
| Value Advantage | Genuine German design and engineering by Siemens AG. Temperature-compensated internal bimetallic mechanics prevent false or early trip errors caused by shifting environmental temperatures inside dense sub-distribution enclosures. Offers field maintenance technicians an exceptionally cost-effective alternative to clear panel faults. |
