Class T (JJN/JLLN/A3T) Fuses

A compact extremely fast-acting fuse ideal for protecting high amperage circuits

A fuses' ability to react to a detected in high amperage circuits is critical to their preservation. To effectively protect battery banks, inverters, and other high amperage circuits, fuses must trip instantly to save components connected to the circuit. Blue Sea Systems designed these Class-T fuses to have an extremely fast reaction to detected faults and offer the best possible protection. Class-T fuses and fuse blocks are compact and easy to install in tight spaces. Available in 110A-400A ratings, these fuses fit any Class-T fuse block . The 200A (5116) has been recently reintroduced to offer more tailored circuit protection. A high interrupt capacity allows these fuses to handle extremely high amperage before catastrophic failure.
