RT PFSL4-1 4 Gauge Linkable Fuse Block Power Distribution

The RT PFSL4-1 is a 4 gauge linkable fuse block designed for automotive, marine, RV, and powersports electrical systems. Part of the RT (Ring Terminal) Series from Egis Mobile Electric, this fuse block accepts a 4 AWG input wire via ring terminal and distributes protected branch circuits through standard ATO/ATC-style blade fuses.

The linkable design allows multiple fuse blocks to be connected together side-by-side, enabling scalable power distribution without running additional main feed wires. This makes the PFSL4-1 ideal for custom wiring builds, upfitter installations, and any application requiring an organized, expandable fuse distribution solution.

Key Features:

• 4 AWG (4 Gauge) input ring terminal connection for high-current main feed wiring
• Linkable design — connects to additional RT Series fuse blocks for expandable circuit distribution
• Accepts standard ATO/ATC blade fuses for easy replacement and broad fuse availability
• High-temperature nylon construction withstands harsh underhood and marine environments
• Stainless steel self-locking hardware provides vibration-resistant, corrosion-resistant connections
• Protective cover guards fuses and terminals from accidental shorts and environmental exposure
• Integrated label recesses for easy circuit identification and organization
• Suitable for 12V and 24V DC systems in automotive, marine, RV, and powersports applications

The RT PFSL4-1 fuse block simplifies branch circuit protection in custom electrical installations, providing a clean, professional-grade distribution point for multiple accessory circuits from a single 4-gauge feed line.
