10-Way Pre-Wired Relay Fuse Distribution Block - Suits 10 x 4/5 Pin Relays & 15 x ATC Blade Fuses

12VS 10-Way Fused Relay Distribution Box | Pre-Wired Edition

Part Number: RELFUSE10PW

Ultimate Convenience. Engineered to Endure.

Tired of messy wiring, unreliable connections, and the headache of adding new accessories to your vehicle? The 12VS 10-Way Fused Relay Distribution Box is here to revolutionize your automotive electrical system by delivering a clean, professional, and plug-and-play solution.

The Pre-Wired Edition is designed for rapid installation. It comes completely assembled with high-quality, pre-terminated internal wiring, eliminating the painstaking task of crimping individual terminals inside the block. Simply connect your primary power feed, trigger switches, and accessory leads, and you are ready to go!

What’s In The Box:

10 x 12V 40A 4-Pin Relays
15 x ATC/ATO Blade Fuses (Features 10 dedicated relay-protected slots plus 5 integrated auxiliary fuse slots for non-switched accessories)
Pre-Wired Internal Harness: Fully pre-terminated internal connections including common power-input links, saving you hours of assembly time.

Key Features & Benefits:

Pre-Wired for Speed: Skip the complexity of crimping and routing internal jumpers. Our pre-terminated block dramatically slashes installation time while guaranteeing a reliable, factory-quality internal connection.
Centralized Power Distribution: Consolidate your accessory wiring, fuses, and switching relays into one neat, heat-resistant housing. Say goodbye to inline fuse holders and spaghetti wiring under the hood.
15-Way Fuse Protection: Features fifteen independent ATO/ATC blade fuse slots. Ten slots protect your relay-driven circuits, while five additional auxiliary slots allow you to fuse low-draw, constant-power accessories (like USB sockets, fridges, or memory feeds) in the exact same block.
Rugged Construction: Engineered to withstand harsh Australian engine bay environments and cabin heat, keeping your vibrating connections secure.
Compact Footprint: Delivers ten-relay management and fifteen fused circuits in an ultra-compact layout, perfect for tight mounting locations in modern 4WDs, canopy builds, boats, and caravans.

Engineering & Derating Specification: Smart Piggyback Power Link

To simplify your install, this pre-wired box features common-feed piggyback bridges linking the main power feeds between the relay sockets. Instead of routing separate heavy-gauge supply lines for every individual relay, a single main input feed powers each linked pair.

What this means for your circuit limits (Derating):

Individual Capability: Each 12V 40A relay is physically capable of switching up to a 40A peak load (or 30A continuous) if wired completely independently.
The Pre-Wired Shared Limit: Because the internal supply bridges consolidate the input feeds, running multiple relays simultaneously at maximum output would overload a single supply line.
Our Recommended Spec: We recommend a derated maximum limit of 30A continuous per circuit when used independently. If you intend to run linked circuits simultaneously, ensure the combined continuous load of any linked pair does not exceed 40A total.

The 12VS Over-Engineering Advantage: By supplying heavy-duty 40A relays as standard in a pre-wired module, we significantly "over-engineer" the switching contacts. Running a 40A-rated relay at our derated 20A–30A limit ensures the internal contacts run exceptionally cool, drastically extending the service life of the relays and preventing the voltage drop common in cheaper, under-spec components.

Why Choose the 12VS Pre-Wired Range?

Maximum Electrical Safety: Protect your valuable electronics and isolate short circuits instantly.
No Specialty Crimp Tools Needed: Because the internal sockets are pre-wired, you don't need expensive open-barrel ratcheting crimpers to assemble the box internals.
Simplified Troubleshooting: Clean layout and independent fusing let you pinpoint issues in seconds.

Don't let disorganized wiring hold you back. Upgrade to the 12VS RELFUSE10PW today and experience the peace of mind that comes with a perfectly engineered, rapidly installed 12-volt system.

Need 100% independent power pathways? If you are running multiple high-draw accessories simultaneously (such as twin high-output air compressors or massive driving light bars) and require full, un-shared 40A continuous capacity per circuit, we recommend our 12VS Unwired Standard Series, which allows you to run independent, dedicated supply lines to each relay.
