7.7.2.1 Overload Calculation
Note:
In the overload procedure measurement of the current is limited to 5 x motor FLA to prevent saturation from
affecting the calculation. Therefore the trip time at 5 x motor FLA will be identical to the trip time at 8 x motor
FLA.
The approximate trip time is calculated as follows:
where:
OLT represents OverLoad Trip setting – (default = 115%).
OLD represents OverLoad Trip Delay – trip delay at 5 x Motor FLA, (default = 4 sec).
Example 1: Motor FLA = 80A, actual current = 120A.
I
%
= 120 x 100 / 80 = 150%
If settings are as in the default then:
Example 2: The same motor and setting, but the current is 400A.
I
%
= 400 x 100 / 80 = 500%
If settings are as in the default then
Example 3: Motor FLA = 80A, actual current = 200A, Overload Delay (OLD) = 10
I
%
= 200 x 100 / 80 = 250%
