got a few here 5/6A, 7.5/8A ,10A and 15A good quality fast blow ones that replace a standard blade fuse but being tall the fuse box lid may not fit when installed.
great for wiring and fault finding jobs as you just push the button to reset them so no piles of blown fuses to get it right.
I have been using them so not new but as new with marks on the blades, £3 each including postage as testing items through paypal or £2.50 at meets/shows.
