Class T fuse protection for high-current marine and DC electrical systems, providing 350A circuit protection with an extremely fast short-circuit response.

Built for use with compatible Class T fuse blocks, this Blue Sea Systems fuse helps protect large battery banks, inverters, and other high-current DC equipment. Its 20,000A interrupt capacity supports fault protection in demanding electrical installations. The fuse is UL listed to standard 248-15 and DC tested to UL standard 198L.

350A rating: Provides circuit protection for appropriately sized high-current DC systems.
Class T construction: Fits compatible Class T fuse blocks for coordinated installation.
Extremely fast short-circuit response: Helps interrupt severe electrical faults quickly.
20,000A interrupt capacity: Supports protection of large battery banks and inverter circuits.
UL listed and DC tested: Meets UL 248-15 listing requirements and UL 198L DC testing requirements.

Install this 350A Class T fuse in a compatible Class T fuse block to protect high-current DC wiring and equipment. It suits marine electrical systems, large battery banks, inverter circuits, and other applications that require high interrupt capacity. The fuse is intended for properly matched circuits, conductors, and fuse holders; verify the electrical system’s required amperage and voltage before installation. Blue Sea Systems identifies compatible 225A–400A fuse blocks including models 5502 and 5502100. The fuse is not a replacement for correct circuit sizing or professional electrical installation.
