RW10-12F & FW10-12F(M) Fuse Manual

The RW10-10F and FW10-12F(M) fuses are designed for 12 kV AC distribution lines and transformers, offering overload and short‑circuit protection for rated load currents. The RW10-12F is a standard type, while the FW10-12F(M) is a salt‑spray‑resistant version for heavily polluted areas.

The document describes the fuse’s two‑part construction (base and arc‑quenching chamber), the bridge‑shaped contacts, spring‑loaded mechanism, and step‑wise venting design. It includes technical specifications, dimensions, operating environment limits, installation procedures, safety precautions, and ordering requirements. This manual is written in Chinese.
