7UT5121-4CB01-0AA0/LL is a Siemens SIPROTEC differential protection relay with a 1 A rated-current input. The nameplate lists 16 2/3 Hz, 50 Hz and 60 Hz rated-frequency options. Auxiliary supply options are marked as 60, 110 and 125 VDC. The exact connection reference is C53207-A318-X1-1*-12. The unit carries CE identification and a fixed-cover operating notice.
7UT5121-4CB01-0AA0/LL evaluates current relationships across the protected zone and issues protection decisions when the configured differential criteria are met. The 7UT512 family is associated with transformer and unit differential-protection applications. Exact suffix matching matters because current input, auxiliary voltage, hardware configuration and terminal assignment vary by order code.
Existing settings and wiring records should be archived before replacement. Commissioning must use the applicable Siemens protection study and connection diagram.
The relay receives the configured 1 A current-transformer signals from the protected zone.
Measured currents are compared according to the protection settings.
A qualifying internal-fault condition produces the configured trip decision.
The relay output initiates the associated breaker or protection action.
