RB-R3F3S-W 3-Way Pre-wired 12V Relay Fuse Box Features
- 3-Circuit Power Distribution
This 3 way relay fuse box provides a centralized control hub for three independent electrical accessories simultaneously. The 3-slot distribution block is specifically designed to manage multiple lighting or power systems through a single, organized unit.
- Plug-and-Play Pre-wiring
A pre-wired relay box eliminates the time-consuming process of crimping terminals and manual wiring for a faster installation. The fully assembled harness allows for immediate connection to your power supply and accessories right out of the box.
- Tailored Multi-Layer Defense
Three 40A 12V relays work in tandem with three assorted blade fuses (10A/20A/30A) to provide dedicated circuit protection. This fused relay kit ensures each of your three high-power devices is individually shielded against overcurrent and short circuits.
- Compact Environmental Protection
The waterproof relay enclosure features a snap-on lid and a sealed bottom to resist moisture and dust intrusion. This compact fuse box fits into tight engine bays or cabins, ensuring your 3-way circuitry remains stable in harsh automotive or marine conditions.
- Versatile Mounting Hardware
Included stainless steel L-brackets provide stable mounting options for cars, trucks, ATVs, and boat electrical systems. The complete mounting kit ensures a professional, vibration-resistant installation that maintains its structural integrity over time.
