| Does this look like a fuse |

While troubleshooting a power supply I found two of these that indicate open. I’m guessing they are fuses. The same ones on a different operating channel are dead shorts. Anyone happen to have a schematic for a R&S 3040 power supply channel? |

Hi! Is it R&S power supply? It also has Fast 7A in parallel. |

Yes, that's a fuse |
