DC fuse rating relationship with fuse size
When the DC voltage increases by 150V, the length of the fuse body should be increased by 10 mm. In turn, when the DC voltage is 1000V, the length of the fuse body should be 70mm. When the DC fuse voltage is 10kv-12kv, the length of the tube body should be at least 600-700mm. Even if the fuse is bent, the length of the tube body should be about 300 mm, otherwise the threat of series arc still exists.
At present, the tube body length of AC fuse 10-12kV at home and abroad is generally 292-442mm. When DC fuse in Europe and America is 2000V DC, the round tube body is 127-190mm, and the square body fuse tube with high current is 170-200mm. All of these are based on the scientific choice of ensuring safe and reliable breaking.
Eaton Bussmann photovoltaic PV solar fuses are designed to protect DC system of 600VDC, 1000VDC, 1500 V d.c. They are suitable for the DC protection of solar panels, combiner boxes, recombiner units and battery storage.
