RW12-35 drop-out fuse cutout

Design

1. Upper terminal clamp (tinned copper casting and tinned stamping).
2. Upper cover (hot-dip tinning 80 µm, thickness 3 mm).
3. Upper contact plate (silver plating 3 µm, thickness 2.5 mm).
4. Upper moving contact (silver plating 3 µm; 304 stainless steel spring withstands high pressure).
5. Operating hook (the fork-shaped hook reliably guides the fuse carrier into the "closed" position).
6. Fuse carrier (UV-resistant, non-hygroscopic, durable).
7. Trunnion (silver plating 3 µm) — the fuse carrier does not wobble sideways on closing, high precision.
8. Lower fixed contact (not visible in the photo): the current path runs through a silver-plated shunt plate and does not pass through the hinge pin.
9. Drop-out mechanism (ensures quick release of the fuse carrier end; the flexible conductor drops out quickly).
10. High-strength insulator (creepage distance 875 mm; self-cleaning surface, high strength, excellent workmanship).

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