Breaking capacity only determines the maximum short-circuit current the fuse can safely cut off — it is not a quality ranking. For small rooftop solar systems with low short-circuit current, standard 10kA gPV fuses fully meet safety requirements at a lower cost.
For large ground PV stations and energy storage systems with high parallel short-circuit current, high breaking capacity 20kA / 30kA fuses are mandatory to avoid arc burning risks. YePV supplies both standard and high breaking capacity gPV fuses for different PV project demands.
Our 1500V DC gPV solar fuse range covers 10A, 15A, 20A, 25A, 30A, 40A, 50A, 60A, 65A, 70A, 80A, 90A and 100A, all built on a 10x38mm gPV body with TÜV, UL, CE and IEC compliance.
