RW33-15 drop-out fuse cutout

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; precise design significantly increases breaking capacity).
3. Top cover (hot-dip galvanized over 80 µm; made integral with the operating hook).
4. Upper moving contact (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 carrier (UV-resistant, non-hygroscopic, durable).
7. Trunnion (3 µm silver plating) — the carrier does not wobble sideways when closing, high precision.
8. Drop-out mechanism (ensures fast release of the carrier end and reduces the force transmitted to the fuse link when closing).
9. High-strength insulator (self-cleaning surface, high strength, excellent workmanship).

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