Blue Sea Class T Fuse Block – 225-400A
The Blue Sea Systems 5502 Class-T Fuse Holder features large tinned copper mounting blocks designed to efficiently dissipate heat. Its four-stud configuration allows easy connection of large cable lugs without interference from the fuse itself. Stainless steel mounting hardware offers excellent corrosion resistance in marine environments. While the clear protective cover insulates and safeguards the fuse terminals.
Class T fuses – use cases
Class-T fuses deliver premium protection for high-power electrical circuits, especially in applications that require ultra-fast fuse response times. Advanced battery technologies, including AGM and lithium batteries, can generate exceptionally high short-circuit currents that may exceed the interrupt capacity of conventional circuit breakers and standard fuse types.
