Digitrip Electronic Trip Units

Circuit Breaker Type	Frame	Ratings
FDE, HFDE, FDCE	225	100, 110, 125, 150, 160, 175, 200, 225
FDE, HFDE, FDCE	160	60, 70, 80, 90, 100, 125, 150, 160
FDE, HFDE, FDCE	80	15, 20, 30, 40, 50, 60, 70, 80

NOTES:
(1) DC ratings apply to substantially non-inductive circuits.
(2) Two-pole circuit breaker, or two poles of three-pole circuit breaker.
(3) Time constant is 3 milliseconds minimum at 10 kA and 8 milliseconds minimum at 22 kA.
(4) Electronics available on three-pole only, no DC rating for FDE, HFDE, FDCE.
(5) Current limiting.
(6) Check with Eaton for availability.
