For the protection and isolation of photovoltaic battery modules or arrays for new energy photovoltaic systems, isolation of junction box, the isolation switch and other suitable circuit system protection. This fuse series has features of small size, low power consumption, high breaking capacity, etc. This fuse series also has superior resistance to high altitude environment, excellent fusing characteristic and durability. This is the first fuse series to satisfy the requirement of higher performance photovoltaic modules in the world.
