Common questions
Buyer FAQ
Does it include the fuse holder?
No. This listing is for one ANL fuse only.
Can I replace a smaller fuse with this 40A fuse?
Only if the equipment manufacturer, conductors and holder all permit the higher rating. Never upsize merely to prevent an opened fuse.
Can I tell whether it has opened by looking?
The element is visible, but isolate the circuit and use an appropriate meter when a conclusive electrical check is needed.
Can I reuse the fuse after it opens?
No. Correct the fault and install a new fuse of the correct type and rating.
