T15AH250V Cartridge Ceramic Fuse 6x30mm 15A 250V for Power Supply repair

T15AH250V Cartridge Ceramic Fuse 6×30 mm – 15A 250V PSU Replacement

Restore overcurrent protection on your mining power supply with the T15AH250V ceramic fuse. Rated at 15 A / 250 V in a 6×30 mm cartridge, it is sized for the heavier-draw input stages found in 3,000 W+ PSUs such as the Whatsminer P21, Bitmain APW11/APW12, and similar units. Ceramic construction provides better arc-quenching energy than glass, preventing housing rupture during high-current fault events.

Tin-Plated Terminals for Reliable Contact

The end caps are tin-plated for corrosion resistance and low contact resistance inside the fuse holder. In a mining farm environment where humidity and dust are constant challenges, tin plating prevents the oxidation layer build-up that can cause nuisance voltage drops and intermittent PSU faults. The ceramic body itself resists moisture and thermal shock far better than glass equivalents.

Diagnosis Before Replacement

A blown 15 A fuse on a high-power PSU usually points to a failed bridge rectifier, shorted bulk capacitor, or MOSFET failure on the primary side. Always test downstream components before installing the new fuse — replacing the fuse alone without fixing the root cause will blow the replacement immediately on power-up.
