Selectivity

The following table shows the conditions to satisfy full
selectivity between UP-STREAM and DOWN-STREAM devices.
Up-stream: M-PACT Plus
Down-stream: M-PACT Plus
ST delay 50 ms minimum between up-stream and downstream
ACB Multiplication coeffi cient between LT-ratings ≥ 1,56

Temperature Deratings

Free Air
The M-PACT Plus ACBs may operate at higher ambient
temperatures than 40°C in certain installation conditions.
In this case the current rating in Amperes should be reduced
as indicated below.
