The 6ES7900-5DA01-0XA0 is a Siemens SIMATIC PG power supply cable, 3 m length, configured for the USA power standard and intended for the Field PG M3 programming device. This is a spare part cable — it replaces the original power cord for the Field PG M3, not a general-purpose IEC lead. The USA variant means it terminates in a NEMA plug.
Listed lifecycle stage is mature, meaning the part remains in the active catalog but is no longer the focus of new development or design-in activity.
