Siemens 3RV20111AA10 Motor Starter Protector
MPN read — 3RV20111AA10 family position
The base part number 3RV20111AA10 places this unit in Siemens' S00 frame motor starter protector (MSP) series, distinguished by the AA suffix indicating screw-type main current terminals without auxiliary contacts. The trailing 10 designates the standard bulk packaging variant. All listed alternates share the 3RV20111 prefix and S00 frame designation, varying only in terminal type, auxiliary contact configuration, or current range within the same mechanical footprint.

- 3RV20111AA15 shares the same 1.6A thermal rating, DIN rail mount, and 3-pole configuration; the AA15 suffix denotes screw terminals with one NO and one NC auxiliary contact block integrated into the housing. Panel builders requiring feedback contacts without separate mounting choose this variant for reduced installation steps.
- 3RV20111AA40 matches 1.6A and DIN rail mount but substitutes ring-lug terminations and adds CE and VDE to the approval suite; breaker type shifts to thermal magnetic, enabling faster short-circuit clearing on inductive motor loads.
- 3RV20111AA20 retains the 1.6A thermal rating and screw terminals of the seed unit but uses spring-clamp main contacts instead, eliminating screw maintenance on vibration-prone machinery or mobile equipment.
Terminal system variants across the S00 frame
The S00 frame supports three distinct main-current termination approaches: screw-type (AA10, AA15, JA10, HA10, DA10), spring-clamp (AA20, AA25, AA200BA0), and ring-lug (AA40). Selection depends on installation environment; spring-clamp suits high-vibration panels; ring-lug accommodates limited wire bend radius. All share the same 45mm width and 97mm height envelope per the S00 standard.
Certification and approval coverage
The seed unit 3RV20111AA10 carries ATEX (explosive atmosphere), CCC (China), CSA (North America), EAC (Eurasian), IECEx (international explosive), and UL (North America) listings. Two alternates (AA40, AA25) add CE and VDE for European low-voltage directive compliance. The AA200BA0 variant drops ATEX, CCC, CSA, IECEx, and UL approvals, retaining only CE, EAC, and VDE—limiting use to regions accepting those three certifications.
