Ceramic Fuse 20A 500V for Bitmain APW11 / Antminer S19 Hydro PSU
Ensure reliable circuit protection for your Antminer S19 Hydro power supplies with the high-quality Ceramic Fuse 20A 500V. Designed as a direct replacement for non-operating fuses on APW111721 power supplies — this fuse delivers a 500VAC rated voltage and 20A rated current.
Compact 6.3 × 32 mm package, specifically engineered to deliver excellent breaking ratings and fast response to fault currents. 20A interrupting rating ensures efficient circuit protection in high-energy applications, safeguarding equipment from potential damage during fault events. DC breaking capability for DC-side fuse applications across hydro PSU rail protection.
Typical Use in Mining PSU Repair
- APW11 / APW111721 input fuse replacement — restoring AC-side circuit protection.
- Post-fault recovery — replacing blown fuses after primary-side fault events.
- S19 Hydro PSU servicing — fuse replacement during full PSU rebuild.
- Production refurbishment — bulk fuse stock for line-based PSU rebuilds.
- Pre-emptive replacement — replacing aged fuses during periodic maintenance.

FAQ — Ceramic Fuse 20A / 500V
Q: Ceramic vs glass fuse — when to use ceramic?
A: Ceramic fuses handle higher interrupting ratings (3-4× glass) and DC-breaking capability — required for higher-energy applications like mining PSU input fuses. Glass fuses are cheaper but limited to lower-energy applications. For APW11 input, ceramic is OEM-spec.
Q: 6.3×32mm vs other sizes?
A: 6.3×32mm is the larger ceramic fuse standard. 5×20mm is smaller (typical low-power applications). 10×38mm is industrial (HVAC, motor drives). The 6.3×32mm fits APW11 PSU input — verify your fuse holder before ordering.
Q: How do I know the fuse blew vs just disconnected?
A: Test with multimeter continuity. Good fuse shows ~0Ω. Blown fuse shows infinite resistance. If your PSU won't start and fuse shows infinite, replace the fuse — but also investigate WHY it blew (failed primary MOSFET, bridge rectifier, surge event) before powering up again.
Q: Bulk pricing for APW11 repair shops?
A: Yes — email contact@lys-sz.com with your monthly PSU rework volume for tier pricing on ceramic fuse stock.
