SEL-751 Settings Sheets
Instruction Manual
These settings sheets include the definition and input range for each setting in the relay. You can access the
settings from the relay front panel and the serial ports. See Section 4: Protection and Logic Functions for
detailed descriptions of the settings.
➤ Some settings require an optional module. Refer to the SEL-751 Model Option Table, and the notes to
the following settings for details on which settings are available in a specific model.
ACSELERATOR
QuickSet SEL-5030 Software, which shows and hides settings depending on the MOT part number
selected, is the best way to view settings available in a specific model.
➤ Some of the settings ranges may be more restrictive than shown, because of settings interdependency
checks performed when new settings are saved.
➤ The settings are not case sensitive.
