Bluesea ANL Fuse Block with Insulating Cover - 35 to 750A 5503
The Bluesea 5503 ANL Fuse Block with insulating cover is engineered for high current DC protection in marine, automotive, RV, and solar energy systems. It is suitable for systems up to 32 V DC and handles ANL (or CNL) fuses in the 35 A to 750 A range.
Constructed with a reinforced polycarbonate base (UL 94-V0 rated) and tin-plated copper bus bars, it offers both electrical performance and safety. Stainless steel studs provide corrosion resistance and maintain high torque contact reliability.
A key design feature is the swing-out insulating cover, which lets you install or swap fuses without fully removing the cover or block. The cover has breakouts in all directions, allowing cable entry from any side, making installations neater and more flexible.
Fuse sold separately.
