Slo Blo Fuse 20 Amp MDA Style 1 1/4" x 1/4"

This Item is a 20Amp Slo Blo MDA Style Ceramic Fuse that measures 1 1/4" Long x 1/4" Wide and is used on some Hot Tub or Pool Boards. This is a smaller automotive style fuse that does not have glass but used ceramic to dissipate heat. You will not be able to see if this fuse is blown you will have to measure across it with a meter. Note: This fuse is really large to be used on a board and sometimes it blows very slowly because of heat and just replacening it will not be a long term solution.
