What is the minimum overload current that can be set on Micrologic 2.2 & 2.3?

The Overload on the Micrologic 2.2 and 2.3 trip units can be adjusted to 0.36 x in

in = nominal current rating of the breaker

For example 100A MCCB can be turned down to 40A initially (adjust the io dial to suit)

From here you can further turn this down to 0.9 of the calculated value above (adjust the ir dial to suit)

100A x 0.4 x 0.9 = 36A

A breakdown of the dial settings can be found on the attached file Page 4/12
