The Blue Sea 5502100 Class T Fuse Block with Insulating Cover allows the use of fast-acting Class T fuses for protecting inverters and other sensitive electronics. It is designed for boaters running high-output inverters who need fast, reliable short-circuit protection rated for serious current.
A four-stud design provides ample clearance around each connecting stud to install large cable lugs without the fuse getting in the way, and stainless steel studs resist corrosion and hold up to high torque. The insulating cover satisfies ABYC/USCG requirements and has breakouts for wire access in any direction. Browse more options in our panels, switches, and circuit breakers category.
