Siemens SIRIUS 3RV1011-1HA10 5.5-8A 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 3RV1011-1HA10 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 specifications and approval panels, upper and lower wire terminal screw slots 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 3RV1011-1HA10 (Instr. Ord. No: 3ZX1012-0RV01-1AA1). Conforms strictly to international safety standards including IEC/EN 60947-2, IEC/EN 60947-4-1 at 50/60Hz, and ATEX Type II (2) G/D / DMT 02 ATEX F001 codes. Certified by UL, CCC, and CE markings. |
| Thermal Adjustment Range | 5.5 – 8 Amps (5.5-8A 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 upstream gL/gG backup fuse rating up to 80A (at 400V) or 50A (at 690V). |
| Short-Circuit Breaking Capacity (Icu) | High performance interrupt capacity: 50 kA at 400V AC and 2 kA at 690V AC system operational voltage parameters. Cat A / AC-3 utilization classification thresholds. |
| Integrated Auxiliary Paths | Features built-in front-facing auxiliary contact terminal screws (including paths 13-14 NO and 23-24 NO) supporting a pilot duty automation status feedback layout. Rated cleanly for safe remote signaling loops and electrical relay interlocking. |
| Wiring & Integration | Compact DIN-rail mountable layout footprint. Terminal blocks accommodate solid or stranded multi-wire tracks (L1-T1 / L2-T2 / L3-T3 / D1-D2 / C1-C2 / NO-NC configuration) 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) using a PZ2 driver. |
| 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. |
