Bussman Series Class T Fuses

about this product

BEP Class-T Fuses provide fast-acting, high-interrupt protection for demanding DC power systems. Engineered for reliability in harsh environments, these compact fuses deliver exceptional short-circuit protection with minimal voltage drop—making them ideal for lithium battery banks, inverters, high-output alternators, and other critical power components.

With their robust construction and rapid blow characteristics, BEP Class-T Fuses help safeguard cables, batteries, and system hardware from catastrophic faults while supporting continuous, high-current operation. Trusted across marine, off-grid, RV, and industrial applications, they offer a safe, proven foundation for modern high-energy installations.
