The AD cylindrical cartridge is a photovoltaic-rated fuse for DC solar string protection circuits. Its steatite ceramic body is engineered to handle the high arc energy generated when breaking DC fault currents at 1000VDC.

The 10x38mm format fits standard cylindrical fuse holders of that size. Package contains one cartridge.
