R3-24 Panel Mount 5x20mm Fuse Holder (10A 250V, Bakelite)
The R3-24 panel mount fuse holder is a screw-type, chassis-mounted 5x20mm fuse holder designed for safety-critical equipment. Its black Bakelite (phenolic) base is UL94V0 flame-retardant, rated 10A at 250V/125V AC/DC, with 50A breaking capacity and 3000VAC dielectric withstand. The threaded barrel mounts through a standard 12mm panel hole and locks with a nut, giving you quick, front-panel fuse replacement on power supplies, appliances and industrial control panels.
