Bussmann TCF80 Cube Fuse

The Bussmann TCF80 Cube Fuse is an 80 A Low-Peak Time-Delay CUBEFuse in Eaton’s Bussmann Series, engineered for compact, reliable protection in low-voltage power-distribution circuits. The cube fuse family employs a dual-element current-limiting design and time-delay operation to tolerate normal inrush while reliably interrupting faults, and the 80 A size is rated for 600 V AC with an interrupting rating up to 300 kA at 600 Vac (and 100 kA at 300 Vdc). Its cube form factor minimizes mounting footprint compared with larger cartridge fuses, a hallmark highlighted in Bussmann’s Low-Peak CUBEFuse literature and aligned with UL Class CF protection. The 80 A variant is represented in the TCF80 lineup, with variants such as TCF80RN available for indicating configurations. This family is documented across Eaton’s Bussmann product pages and catalogs, underscoring its role as a space-efficient, high-current protection solution for industrial applications like distribution blocks and switchgear in demanding environments.
