Frequently asked questions
How do I choose the right current rating?
Select a rating above the normal operating current of the circuit but below the maximum current that the wiring and components can safely carry. A fuse that is too large will not protect the circuit.
Does the listing state a voltage rating?
No voltage rating is given in the listing. Check the marking on the fuse or the specifications of the equipment before use.
