    what fuse is this? 612 25A 250V

    Hi gang. I have a Pro Series 20 AMP Battery Charger. Cabela's Brand, made by Pro Mariner.

    Nowhere in the manual does it reference these fuses. But here is the one I pulled out. Can you advise where I can get it?

    It's a 3AG 25 amp fuse, looks like some kind of slow-blow, also looks like a nail wrapped in solder.

    3AG only describes a glass tube fuse's physical size ...... meaning a size 3, American automotive glass fuse.

    --------------
    The direct replacement for the pictured fuse seems is a Cartridge miniature fuse; Time-Lag (T)612 series fuse .......and is to be rated at 250V AC and 25 amperes.

    see http://www.betterfuse.com/MyUploadFi...t_20160620.pdf

    You could contact the charger manufacturer for a replacement. If in a hurry, this may be an acceptable substitution though is rated at 32VAC:

    The voltage rating is predicated on the arc sustainability if the fuse blows. If it's 200VAC it will be designed to make an air gap that 200 volts won't jump.
