MF-528 5x20mm Panel Mount Fuse Holder 10A 250VAC/125VDC
The MF-528 is a 5x20mm panel mount fuse holder designed for front-panel installation with M12.5 threaded fixing. It accepts standard 5x20mm cylindrical fuses and is rated 10A at 250VAC or 125VDC.
This fuse holder uses PBT (polybutylene terephthalate) base material rated UL 94 V0 for reliable flame retardant performance. It features phosphor copper terminals of 0.5mm thickness for stable electrical contact. Besides, it withstands 3000VAC dielectric voltage and maintains insulation resistance above 100MΩ.
The MF-528 has an interrupt capacity of 50A and contact resistance below 5mΩ. It mounts through a Ø12.7mm panel hole with an M12.5 thread and lock nut. The compact overall length of 31.8mm suits space-limited panel designs.
