RW12-15F drop-out fuse cutout with arc chute

Design

1. Upper terminal clamp (3 µm tin plating; double-groove design, integral with the upper contact plate — improved conductivity).
2. Pressure-relief cap (tin-plated; precision design significantly increases breaking capacity).
3. Top cover (hot-dip galvanised over 80 µm; integral with the operating hook).
4. Upper contact plate (3 µm silver plating, integral with the upper terminal clamp — improved conductivity).
5. Upper moving contact rod (3 µm silver plating, tightly fitted into the cast part in the middle — improved conductivity).
6. Fuse tube (UV-resistant, non-non-hygroscopic, durable).
7. Lower fixed contact (3 µm silver plating; prevents lateral swaying of the fuse tube during closing, ensures accurate positioning).
8. Drop-out mechanism (ensures rapid release of the fuse tube end and reduces the force transmitted to the fuse link during closing).
9. High-strength insulator (self-cleaning surface, high strength, excellent workmanship).
10. Arc-quenching grid (high-quality ABS plastic with flame-retardant additives; confines the arc and ensures its de-ionisation).

Note: all iron parts are hot-dip galvanised (coating thickness over 80 µm), fasteners are stainless steel — high-quality grade 304; cast parts — optionally precision-cast brass or aluminium bronze.
