Picture showing what I believe is a real SIBA and the one I just bought. All of the SIBA fuses that have came in meters I have, have this same LOGO. Someone had posted the SIBA now has a factory in China. Did the logo change for that factory? |

Looking closely, I'm fairly sure mine are fake. The printing is well below German standards. Oh, well. It would be interesting to know how the fakes perform. There's no reason why they can't do a reasonable job - it's just meltable metal and sand. |

I'm not intending to use the meter on AC mains but it would be interesting to know if the fuses are fake. :popcorn: --- End quote --- I have to believe you are not alone in your idea that if you don't use the meter on mains that there's no problem. I can see this actually being the majority. I have enough data to say that the fuse is a counterfeit or SIBA has no quality control. I think rather run the second fuse on the half cycle transient generator where most people will think, that's not something I will ever do, I will run a low current time test on it. Something that hobbyist's could experience. The OEM parts have time rating curves. Say the real fuse will blow in a maximum of 10ms with 4X over the trip current applied and the cloned fuse takes 100ms to open. The circuit the fuse is protecting may become damaged. So no half cycle line test. |
