6 Way Pre-Wired Fuse Relay Box with A/C Fan Relay
Product Overview
The 6 Way Pre-Wired Fuse Relay Box with A/C Fan Relay is designed for automotive auxiliary power distribution, circuit protection, and multi-device relay control.
It integrates 6 ATC/ATO blade fuse positions, 5 standard automotive relay positions, and 1 dedicated A/C fan relay position into one compact enclosure.
The pre-wired harness reduces terminal crimping, relay socket assembly, and complicated manual wiring, helping installers save installation time and create a cleaner, more organized electrical system.
The five standard relay circuits can be used for auxiliary lighting, horns, pumps, fans, and other electrical accessories, while the dedicated A/C fan relay circuit is designed for applications such as automotive air-conditioning condenser fans, auxiliary cooling fans, and related high-load fan control systems.
Relay specifications can be selected according to customer requirements. Available relay configurations may include approximately 12V to 72V and 30A to 60A, depending on relay model, wiring specification, load requirements, and project design.
FUZTRAX can supply the product as a complete pre-wired assembly or provide the housing, terminals, relays, fuses, and related components separately for OEM, ODM, wiring harness manufacturing, and custom vehicle electrical projects.
Key Features
6 Fuse Positions
The integrated fuse block provides six ATC/ATO blade fuse positions for centralized circuit protection.
Different fuse ratings can be selected according to the actual operating current of each connected accessory.
This helps organize multiple protected circuits in one compact location while making fuse inspection and replacement easier.
5 Standard Relay Positions
Five standard automotive relay positions provide independent switching control for multiple auxiliary electrical accessories.
Typical applications include:
The relay-controlled circuits can be configured according to the customer's electrical system and wiring requirements.
Dedicated A/C Fan Relay
In addition to the five standard relay positions, the unit includes one dedicated relay circuit for A/C fan and cooling fan applications.
This circuit can be used for:
The dedicated fan relay configuration provides a more integrated solution for projects that require both general accessory control and fan switching within the same fuse relay box.
Relay and wiring specifications should always be selected according to the actual fan starting current, continuous operating current, and system voltage.
Pre-Wired for Faster Installation
The pre-installed wiring harness helps reduce repetitive terminal crimping, relay socket wiring, and manual assembly.
Color-coded wiring can make circuit identification easier and reduce installation errors.
For OEM and ODM projects, wire gauge, wire color, wire length, terminal configuration, and wiring layout can be customized according to customer requirements.
Flexible Relay Configurations
Relay specifications can be selected according to the electrical requirements of the application.
Available options may include:
Different relay specifications may be used for the standard accessory circuits and the dedicated A/C fan circuit depending on the application.
Final relay selection should be based on:
ATC / ATO Blade Fuse Compatible
The fuse block is compatible with commonly used ATC/ATO automotive blade fuses.
Fuse ratings can be configured independently for different circuits according to the electrical load.
This makes the product suitable for automotive aftermarket installation, custom wiring, vehicle modification, and OEM electrical integration.
Compact Integrated Design
Instead of installing separate fuse holders, individual relays, fan relays, and loose wiring throughout the vehicle, this fuse relay box integrates major protection and switching components into one enclosure.
The centralized layout helps reduce scattered wiring and provides a cleaner and more professional electrical installation.
Protective Top Cover
The fitted top cover helps protect the fuses, relays, and electrical terminals from dust, dirt, debris, and accidental contact.
This product is not waterproof.
It should be installed in a dry or protected location and should not be directly exposed to rain, water spray, high-pressure water, or immersion.
Optional Bottom Cover
An optional bottom cover is available for customers who require additional protection for the lower terminals and wiring area.
The bottom cover can provide a more complete enclosure structure and cleaner appearance for OEM assemblies and custom wiring projects.
Bottom Cover Minimum Order Quantity
MOQ: 500 sets
The optional bottom cover is available for orders of 500 sets or more.
Orders below this quantity are normally supplied without the optional bottom cover unless otherwise confirmed.

Why Choose This Configuration?
This configuration is designed for electrical systems that require several independently controlled accessories together with a dedicated cooling or A/C fan circuit.
The five standard relay positions provide flexible control for common vehicle accessories, while the dedicated fan relay circuit allows the cooling system to be integrated into the same centralized fuse relay box.
Compared with installing multiple standalone relays, fuse holders, and a separate fan relay, the integrated design helps reduce wiring complexity and keeps the electrical system more organized.
It is particularly suitable for custom vehicles, off-road builds, classic car upgrades, engine conversions, air-conditioning system upgrades, and OEM electrical projects.
OEM & ODM Customization
FUZTRAX provides OEM and ODM manufacturing services for automotive fuse boxes, relay boxes, wiring harnesses, terminals, and related electrical assemblies.
Customization options include:
Customers can order complete pre-wired assemblies or select individual components according to their own manufacturing and assembly requirements.
For projects requiring the optional bottom cover, the minimum order quantity is 500 sets.
Important Electrical Notice
The current rating printed on a relay represents the relay contact specification and does not automatically represent the safe continuous current capacity of the complete fuse relay box or wiring harness.
A/C condenser fans and cooling fans may have significantly higher starting current than their normal continuous operating current.
Actual allowable circuit current depends on several factors, including:
-
Wire cross-sectional area
-
Fuse rating
-
Relay contact rating
-
Terminal capacity
-
Connector capacity
-
Motor starting current
-
Continuous operating current
-
Ambient temperature
-
Installation method
-
Electrical load characteristics
Always select the appropriate relay, fuse, wire gauge, terminals, and connectors according to the actual electrical requirements of the connected equipment.
For A/C fan, radiator fan, high-current motor, or specialized electrical applications, confirm the required operating current and starting current before ordering.
