The 100 mA and 10 A inputs are protected by user-replaceable fuses.
•
The 100 mA input is protected by a fuse (A1F2) rated at 440 mA, 1000 V (fast
blow), 10,000 A minimum breaking capacity.
•
The 10 A input is protected by a fuse (A1F1) rated at 11 A, 1000 V (fast blow),
10,000 A minimum breaking capacity.
