A 6 relay fuse box combines six 12V 40A automotive relays with six ATO/ATC blade fuse positions and a pre-wired harness in one organized electrical control assembly. The 4-pin normally open relays use terminals 30, 85, 86 and 87, making the unit suitable for centralized switching and fuse protection in 12V vehicle accessory circuits.

A 6 relay fuse box combines six automotive relays, six blade fuse positions and a pre-wired wiring harness within one centralized electrical control assembly. This configuration helps organize multiple switched accessory circuits while providing dedicated fuse positions for circuit protection.
The box uses six 12V 40A 4-pin automotive relays with terminals 30, 85, 86 and 87 in a normally open configuration. Six fuse positions are designed for standard ATO/ATC blade fuses.

A 6 relay fuse box is suitable for 12V electrical systems where several accessories require both relay switching and individual fuse protection.
The relays and fuses perform different functions within the electrical system. Each relay allows a low-current control circuit to switch a higher-current accessory circuit, while the fuse positions provide overcurrent protection for the connected wiring and loads.
A 6 relay fuse box centralizes these functions within one panel, helping reduce scattered relay sockets, inline fuse holders and loose wiring in multi-accessory installations.
The supplied relays use the standard four-pin automotive layout:
When the relay coil is energized through terminals 85 and 86, the contact closes between terminals 30 and 87 and supplies power to the controlled load.
Installing six separate relays, sockets, fuse holders and wiring individually can create a large number of loose connections and make the electrical system harder to organize.
This 6 relay fuse box uses a pre-wired harness to bring the relay and fuse circuits together within one assembly, helping simplify installation, circuit identification and future servicing.
The fuse rating for each circuit should be selected according to the connected load, conductor size and circuit protection requirements. The presence of six fuse positions does not mean that all six circuits should use the same fuse rating.
Fuse color alone should not be used to determine the required current rating. Always verify the fuse marking and the electrical requirements of the protected circuit.
The relays are rated at 12V DC and 40A. The 40A value describes the relay rating and should not be interpreted as the required operating current of every connected accessory.
Relay capacity, fuse rating, wire size and actual load current should be evaluated together when designing the complete circuit.
Individual relay sockets can work well for one or two circuits, but multiple separate relay sockets and fuse holders can make larger wiring systems difficult to organize.
A 6 relay fuse box groups six relay-controlled circuits and six fuse positions into one panel, providing a more centralized arrangement for multi-accessory vehicle wiring.
The assembly uses six automotive relays, each rated at 12V and 40A.
The six fuse positions are designed for standard ATO/ATC blade fuses.
Pins 85 and 86 operate the relay coil, while pin 30 is the common power contact and pin 87 is the normally open switched output.
No. The 40A value is the relay rating. Actual circuit current depends on the connected load, conductor size, fuse selection and complete electrical design.
A pre-wired relay box reduces the amount of separate relay sockets, fuse holders and loose wiring that need to be installed individually, helping create a more organized electrical system.
