15 Way 10-Relay Pre-Wired Fuse Box
Product Overview
The 15 Way 10-Relay Pre-Wired Fuse Box is a high-capacity automotive power distribution and circuit control solution designed for vehicles and equipment with multiple auxiliary electrical accessories.
It integrates 15 ATC/ATO blade fuse positions and 10 automotive relay positions into one enclosure, providing centralized circuit protection, relay switching, and organized power distribution for complex DC electrical systems.
The pre-wired harness reduces terminal crimping, relay socket assembly, and repetitive manual wiring, helping installers save assembly time and create a cleaner, more professional electrical layout.
Ten circuits can be configured with relay-controlled switching, while the remaining fuse positions can be used for additional protected power circuits according to the customer's wiring design.
Relay configurations are available for 12V and 24V systems, with relay current ratings from approximately 30A to 60A, depending on relay model, wiring specification, load characteristics, and project requirements.
FUZTRAX can supply this product as a complete pre-wired assembly or provide housing, terminals, relays, fuses, and related components separately for OEM, ODM, wiring harness manufacturers, vehicle builders, and aftermarket electrical suppliers.
 
Key Features
15 Fuse Positions + 10 Relay Positions
The integrated design combines fifteen ATC/ATO blade fuse positions and ten automotive relay positions in one enclosure.

Pre-Wired for Faster Installation
The pre-installed wiring harness helps reduce repetitive terminal crimping, relay socket wiring, and manual assembly.
Color-coded wiring makes circuit identification easier and helps reduce installation errors.
For OEM and ODM projects, wiring specifications can be customized according to the customer's vehicle, equipment, or electrical system requirements.
Available wiring customization may include:
-
Wire gauge
-
Wire length
-
Wire color
-
Terminal configuration

Circuit grouping
-
Power input arrangement
10 Independent Relay-Controlled Circuits
Ten relay positions provide independent switching control for multiple electrical accessories.
Typical relay-controlled applications include:
The ten relay circuits can be configured according to the customer's actual system requirements.
Additional Fuse-Protected Circuits
The unit includes fifteen fuse positions and ten relay positions.
This allows the remaining fuse positions to be used for protected circuits that do not require relay switching.
These circuits may be used for:
This flexible layout makes the product suitable for more complex automotive and equipment electrical systems.
12V / 24V Relay Options
Relay configurations are available for common automotive and equipment electrical systems.
Available voltage options include:
Available relay current ratings may include:
Relay models and contact configurations can be selected according to customer requirements.
Final relay selection should be based on:
-
System voltage
-
Continuous operating current
-
Starting or inrush current
-
Wire gauge
-
Fuse rating
-
Terminal capacity
-
Connector capacity
-
Installation environment
-
Electrical load characteristics
ATC / ATO Blade Fuse Compatible
The fuse block is compatible with commonly used ATC/ATO automotive blade fuses.
Different fuse ratings can be selected for individual circuits according to the actual operating current of the connected equipment.
The standardized fuse format makes inspection, replacement, and maintenance convenient for automotive aftermarket and custom wiring applications.
Centralized High-Capacity Power Distribution
Complex vehicle electrical systems may require multiple relays, fuse holders, terminals, and wiring connections.
The 15 Way 10-Relay Fuse Box centralizes major circuit protection and switching components into one enclosure.
This helps reduce scattered relays and inline fuse holders, simplifies circuit management, and creates a cleaner 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.
Do not expose the product directly to rain, continuous water spray, high-pressure washing, or immersion.

Why Choose the 15 Way 10-Relay Configuration?
The 15 Way 10-Relay configuration is designed for vehicles and equipment that require a large number of protected circuits together with extensive relay-controlled switching.
The fifteen fuse positions provide enough capacity for complex auxiliary electrical systems, while ten relay positions allow multiple higher-current or independently controlled accessories to be managed from one centralized enclosure.
The remaining fuse positions can be used for circuits that require fuse protection without relay switching, giving system designers greater flexibility when planning the electrical layout.
Compared with installing numerous standalone relays and inline fuse holders throughout the vehicle, the integrated design helps simplify wiring, reduce installation clutter, and improve long-term circuit organization.
This configuration is particularly suitable for:
-
Large off-road builds
-
Pickup truck electrical upgrades
-
SUV modification projects
-
RV electrical systems
-
Utility vehicles
-
Special-purpose vehicles
-
Custom vehicle projects
-
OEM electrical assemblies
-
Multi-accessory DC power systems
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 a complete pre-wired product or purchase the housing, terminals, relays, fuses, and other related components separately according to their own production and assembly requirements.
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.
Actual allowable circuit current depends on multiple factors, including:
-
Wire cross-sectional area
-
Fuse rating
-
Relay contact rating
-
Terminal capacity
-
Connector capacity
-
Continuous operating current
-
Starting or inrush current
-
Ambient temperature
-
Installation method
-
Electrical load characteristics
Always select the correct relay, fuse, wire gauge, terminals, and connectors according to the actual electrical requirements of the connected equipment.
For high-current, motor-driven, or specialized electrical applications, confirm the complete electrical specifications before ordering.
