Product Positioning

3RT1975-5AB31-WH is a replaceable operating coil used in Siemens SIRIUS S12 base-mounted large contactors (3RT107, 3RT127, 3RT147 series). Its base rated voltage is 23-26V (nominal 24V) AC/DC, making it the lowest voltage version in the series. It is commonly used in 24V circuits within control panels. The "-WH" at the end of the part number, according to publicly available information, indicates an internal Siemens version or ordering notation. Its exact definition cannot be confirmed with current information. The electrical specifications and applicable base size are consistent with the standard 3RT1975-5AB31. It is recommended to provide the complete part number when ordering to facilitate verification by sales personnel.

Core Product Advantages and Features
24V AC/DC low voltage specification
Rated voltage 23-26V (nominal 24V), AC/DC universal, is a common choice for 24V circuits in control panels.
Compatible with SIRIUS S12 base
