Notes
I
n
= Rating plug rating.
I
r
= Long delay setting.
1
310+ trip units have selectable settings instead of a rating plug.
2
310+ trip units have adjustable long delay times of 2–24 seconds, except NG 310+ for 800 A frame, for which it is 2–14 seconds.
3
310+ details are included by frame in Pages V4-T2-44 (JG), V4-T2-62 (LG), V4-T2-72 (NG), and V4-T2-83 (RG).
