Answer Posted / paul
I am not aware of Class 10A, I am aware of Class 5, 10, 15,
20, 25 & 30. These refer to the tripping curve of a
thermal/electronic relay - eg Class 10 means 6 x motor full
load current (FLC) for 10 seconds (normal squirrel cage
induction motor). Therefore Class 30 means 6 x FLC for 30
seconds and Class 5 means 6 x FLC for 5 seconds etc....
