NOTES:
D Using cause of trip module (catalog number TRIP-LED).
® Using ammeter or remote ammeter/cause of trip display (catalog number DIGIVIEW and DIGIVIEWR06).
In = Rating plug rating.
Ir = Long delay setting.
(1) JG- and LG-Frames have selectable settings instead of a rating plug.
(2) JG-, LG- and NG-Frames have adjustable long delay times of 2–24 seconds.
(3) JG/LG: 2X–14X (In); NG: 2X–8X (In); RG: 2X–8X (In); 2500 ampere RG-Frame 200–600% x (In).
(4) JG-Frame also has a 14X setting.
(5) LS, LSG only.
(6) Not to exceed 1200 amperes.
(7) JG- and LG-Frames are Instantaneous, 120 ms. NG- and RG-Frames are Instantaneous, 100, 300 and 500 ms.
