Cooper Bussmann 170L2218 is an industrial cartridge fuse specified for 100 A at 660 V in a 22 × 58 mm body size, a high-current protection device commonly used in industrial power distribution networks. The 22 × 58 mm footprint is a standard Bussmann size across high-current fuses, and catalogs list devices in this form factor with voltages up to 660 Vac, which aligns with this model's rating. Public listings identify this exact variant as a 100 A, 660 V version, consistent with Bussmann's line of 22 × 58 mm industrial fuses designed to protect electrical circuits and equipment operating at or below 660 V.
