Hello, here are the markings embedded into metal parts of the 0.5 A fuse I use for 1.2 A power supply: One one end: 500mA 250V On the other end: FSL (+ some characters that I cannot reproduce on the keyboard) Since I purchased this fuse in the package that said Slow-Blow Fuses/0.5 A , I assume these are correct markings for that. Regards, Zoran
