    Default Fuse Codes cylinder type

    Hi all,
    I have a blown fuse of the glass cylinder type and need to know what to replace it with.
    It is from a wax heater [from a beauty salon] that is 250V 50 W rated.
    The fuse has on one end F630mAL 250V
    The 250V is easy enough but the rest is unknown
    I have a jaycar catalogue but they have M205, 3AG and 5AG fuses in various ratings listed only.
    Any help?

    Thanks buddy
    I think you're right, not sure of the difference between AG and AL though.
    It sure looks similar. I'll get it and try
    Cheers

    250V @ 50 W = 200mA
    By reading this, you have already given me control over a tiny slice of your mind

    The fuse has on one end F630mAL 250V
    It stands for 630mA and F is for fast.

    You may find it difficult to source a 630mA fuse - just put a 1 amp fuse in its place - it will be fine. Find one that fits - ie the appropriate physical size, and yes, F = fast blow.

    As covert pointed out, the device uses 200mA. So if a 630mA fuse burnt out, I would have second thoughts about putting in a 1A fuse!
    If it is just a heater without a motor or transformer, then there is no need to account for an additional startup current.

    250W is plenty of power to start a fire without the fuse blowing.
    If you can't get the 630mA (it is a standard value) then I would suggest to use 500mA.
