The Siemens 6ES7900-0BA00-0XA0 is a UK-specific AC power cable for SIMATIC HMI, IPC, and other devices that take a standard C13 (kettle-lead) inlet. It mates a 90° male BS 1363 plug on the line side to a 180° female C13 connector on the device side, with a 3 m black sheath cable. The cable is rated for indoor use and carries an internal 13 A melting fuse inside the BS 1363 plug — that's the standard UK plug fuse for protection of the cord, not the connected equipment. It's suited for any device with a corresponding AC interface.
Carries CE mark for the European market, CSA approval (N11419) for Canada, CCC certification for China, and KC approval (KTL SW04001-6001) for South Korea. RoHS conformity is confirmed.
