Installation & Selection Notes
- Disconnect main power supply before installation or replacement to prevent short‑circuit hazard.
- Strictly control mounting torque at 12.0Nm ±1Nm; insufficient torque will cause over‑heating risk.
- Inspect fuse blown‑status through the transparent visible‑melting‑element window.
- Select fuse rated current to be 1.1‑1.25 times of circuit continuous working‑current, never over‑rate.
- Only replace with identical ANL‑A model specification for guaranteed protection‑performance.
