WUPP 12-Circuit Fuse Block Panel — 24-Fuse Kit with Waterproof Cover & LED Indicators

WUPP’s 12-circuit fuse block is a compact, marine-grade DC distribution panel with individual LED indicators, a negative bus, and a waterproof cover to protect and organize vehicle and boat electrical systems.

This panel centralizes up to twelve fused circuits for 12–24V systems, combining visual fault detection with corrosion-resistant components and a flame-retardant base. It replaces scattered inline fuses and messy wiring runs with a tidy block that simplifies troubleshooting and keeps circuits accessible for maintenance or upgrades.

How does the LED diagnostic indicator speed up troubleshooting?

The integrated LEDs light when a fuse opens or when a short occurs, so you can immediately spot which circuit needs attention without testing each line individually. This reduces downtime and prevents fishing through bundles of wires to find a problem.

• One LED per circuit for instant visual identification of blown fuses.
• Diagnostic design reduces time spent with multimeters or probes.
• Note: small residual voltage readings may appear with no fuse due to LED circuit resistance.

What materials and ratings make it suitable for marine and automotive use?

The block uses nickel-plated copper busbars and fuse holders for improved conductivity and corrosion resistance, and a PBT flame-retardant housing to withstand heat and mechanical stress. Electrical ratings support typical vehicle and boat applications without overspecifying components.

• Voltage compatibility: 12–32 V DC, suitable for 12V and 24V systems.
• Total continuous current: up to 100A; up to 30A per individual circuit.
• PBT base resists heat, cracking, and combustion better than basic plastics.

How does this product simplify wiring and system layout?

Instead of multiple inline fuse holders and scattered grounds, the panel provides twelve fused outputs and a dedicated negative bus to centralize wiring and ground connections. That organization produces a cleaner installation and makes future changes easier.

• 12 fused outputs arranged for tidy branch wiring runs.
• Included negative bus for consolidated grounding and fewer ground points.
• Mounting screws and labels included for a professional-looking setup.

What comes in the package and how ready is it for installation?

The kit includes everything needed to get started: the 12-circuit block, a selection of blade fuses, mounting hardware, and identification labels. That lets you install and protect multiple accessories immediately after wiring.

• 12-circuit fuse block with waterproof cover and negative bus installed.
• Fuses: 20A ×6, 15A ×6, 10A ×6, 5A ×6 (24 fuses total).
• Includes screws and labels to secure and identify circuits at the panel.

Who is this for? Installers, boat owners, RV enthusiasts, and DIY mechanics who want a tidy, dependable way to manage several DC accessories will find this WUPP fuse block useful. It suits those upgrading from single inline fuses, retrofitting a custom electrical locker, or building out accessory circuits on cars, trucks, boats, and RVs. If you need centralized protection, simple diagnostics, and corrosion-resistant hardware for 12–24V systems, this panel gives a compact professional solution without complex wiring gear.
