The 3RK1301-0CB20-0AB4 is a Siemens SIRIUS ET 200S High Feature direct soft starter identified for motor-starter applications in ET 200S configurations. Siemens specifies this version with a 2.4 to 16 A setting range, electronic switching, electronic protection, and AC-3 operation up to 7.5 kW at 400 V.
For industrial spare-parts purchasing, the complete article number is the key reference for distinguishing this version from other ET 200S starter modules with different current ranges or switching functions.

Inventory & Replacement Notes
The 3RK1301-0CB20-0AB4 is particularly relevant when an existing ET 200S installation still uses the original motor-starter architecture. Siemens notes that the ET 200S system has been cancelled, with the ET 200SP system and its compact motor starter modules serving as the successor platform.
For spare-parts procurement, however, the original 3RK1301 article number remains important when the installed equipment requires the same ET 200S configuration.
Before ordering, compare:
- Complete Siemens article number
- Existing ET 200S configuration
- Motor current requirement
- Starter type
- Installed expansion modules
- Existing spare-parts records
