Blue Sea 5502100 Class T Fuse Block – 225-400A

Description

The Blue Sea 5502100 Class T Fuse Block is designed for fast-acting high-current protection of inverters, chargers, and other sensitive marine electronics. It accepts Class T fuses in the 225A to 400A range and provides a secure connection point for large battery cables and high-energy DC circuits.

The four-stud design leaves ample room around the cable terminals so large lugs can be installed without interfering with the fuse. Tin-plated copper fuse-mounting blocks provide high conductivity, while stainless steel studs and one-piece flange nuts resist corrosion and maintain secure high-torque connections. The high-temperature UL 94-V0 base is designed to withstand the heat generated in demanding fuse applications.

An insulating cover satisfies applicable ABYC and USCG insulation requirements and includes breakouts so cables can enter from multiple directions. The block supports cable sizes up to 4/0 AWG and is ignition protected for marine installation. For high-current circuits where fast Class T protection is preferred, the 5502100 provides a compact, serviceable fuse mounting solution. We carry more in our bus bars & power distribution.
