The following table shows the conditions to satisfy
full selectivity between UP-STREAM and
DOWN-STREAM devices.
Up-stream: M-PACT
Down-stream: M-PACT
ST delay 50 ms minimum between up-stream and
down-stream ACB Multiplication coefficient between
LT-ratings ≥ 1,56
Up-stream: M-PACT
Down-stream: RECORD or SPECTRA*
ST delay 50 ms minimum on M-PACT
Multiplication coefficient between LT ratings
*Record and Spectra are GE Power Controls
