Introduction and Specifications
SEL-351A Models
SEL-351A Models
This instruction manual covers the SEL-351A models listed in Table 1.1.
The model numbers are derived from the SEL-351A ordering information
sheet. The model numbers in Table 1.1 and Table 1 .2 are only the first part of
an actual ordering number—enough to distinguish one model type from
another. These numbers should not be used to order an SEL-351A. To order an
SEL-351A, refer to the actual ordering information sheets.
NOTE: IN current input options 0.2 A
and 0.05 A are not supported in the
SEL-351A-1.
Any SEL-351A model can be ordered with the more sensitive neutral channel
(IN) current input options (0.2 A or 0.05 A nominal). Table 4.1 and
accompanying note show the particular ground directional elements available
with different options of the neutral channel (IN) current input. The 0.05 A
nominal neutral channel (IN) current input option is a legacy nondirectional
sensitive earth fault (SEF) option (the 0.2 A nominal neutral channel (IN)
current input option can provide the same SEF function and additional
directional options, as detailed in Table 4.1).
