Class T fuse for high-current DC circuit protection in marine, RV, and automotive electrical systems, with rapid short-circuit response and a 20,000 A interrupt capacity.

The Blue Sea Systems 5112 is a 110A Class T fuse intended for use with compatible Class T fuse blocks. Its fast-acting response helps limit fault current quickly, while the 20,000A interrupt capacity supports protection for high-current battery banks, inverters, and related DC equipment. The fuse is UL listed to standard 248-15 and DC tested to UL 198L.

  • 110A Class T rating: Provides dedicated overcurrent protection for high-current DC circuits.
  • Extremely fast short-circuit response: Helps interrupt fault current quickly to protect connected wiring and equipment.
  • 20,000A interrupt capacity: Supports high fault-current protection in demanding battery and inverter installations.
  • UL listed to 248-15: Provides recognized fuse construction and performance compliance.
  • DC tested to UL 198L: Supports use in DC electrical protection applications.
  • Compatible fuse-block format: The 110–200A size range uses the Blue Sea Systems 5007100 Class T fuse block.
This 110A Class T fuse is suited to high-current DC power distribution where rapid fault interruption matters. Typical applications include marine electrical systems, RV and automotive power systems, main battery protection, inverter circuits, and other DC equipment requiring a Class T fuse.
