1.Product Overview:
1)The HRW11-12 drop-out fuse cutout ranks at the highest level among international cutout products after several improvements and optimizations.
2)It features a firm and strong structure with accurate fitting.
3)The interrupting current capability is up to 12.5kA.
2.Condition of Use:
1)Ambient air temperatures: Within the range of -30°C to +40°C.
2)Altitude above sea level: Not exceeding 1,000m (if higher, adjustments are needed).
3)Frequency of the A.C. power supply: Not less than 48Hz and not exceeding 52Hz.
3.Structure features:
1)The fuse consists of a base and an arc-extinguishing device.
2)Working contacts are designed in a bridge shape.
3)The fuse tube has a spring bracket at the lower end to maintain tension, ensuring self-locking when the arc-extinguishing tube is in the closed position.
4)During overload or short circuit, the fuse wire melts, and the spring bracket rapidly pulls the fuse wire out of the arc-extinguishing tube, minimizing arcing time and preserving arc-extinguishing material.
