picked this up from Jaycar 30a/12awg fuse holder for 10a blade minis, should it be okay?
I sure hope so.
Best to have one without the ‘Blown Fuse LED’ if possible. The LED on the bottom is meant to illuminate when the fuse breaks.
The LED and resistor is designed for 12-24V. It may go pop at 48V, although will likely burn bright before it does, either way, until the fuse blows it won’t matter that it’s there, and if it does Blow the LED going too wouldn’t be catastrophic to anything else.
