DC Fuse Distribution Modules
Reliable Circuit Protection and Power Distribution
DC Fuse Distribution Modules provide safe and efficient DC power branching with built-in fuse protection.
Available in 4, 6, and 8 channelsそして two connection types — screw or spring clamp, these modules simplify wiring and ensure circuit reliability in industrial, solar, and vehicle systems.
A DC Fuse Distribution Module is a compact device designed to split and protect DC power circuits within control panels or electrical systems.Each channel integrates a fuse holder and LED indicator, allowing quick identification of circuit faults without affecting other lines.When overload or short-circuit occurs, the fuse automatically disconnects that channel, ensuring the rest of the system continues to operate safely.
These modules combine power distribution, overcurrent protection, and clear visual monitoring in one compact DIN-rail unit.They are widely used in industrial automation, solar energy systems, battery cabinets, and vehicle DC applications, helping engineers simplify wiring and enhance electrical safety.
AOSI offers two connection types for its DC Fuse Distribution Modules — ネジ端子 そして バネ端子 — each suited to different wiring preferences and application needs.
Screw terminal fuse modules provide strong mechanical fastening for high-vibration environments. This design is preferred in industrial control panels, vehicle systems, or anywhere wiring is subject to movement or thermal expansion.
Firm mechanical connection, resistant to vibration
Suitable for thicker wires or ring terminals
Ideal for fixed cabinet installations
Spring terminal fuse modules use a push-in or press-fit design, allowing tool-free and faster wiring. This type is popular in modern automation panels where quick maintenance and high wiring density are important.
Quick, tool-free wiring
Consistent clamping force, even under vibration
Easier re-wiring and maintenance on site
要するにだ、 ネジ端子 prioritize mechanical strength, while バネ端子 emphasize speed and flexibility.
Both types are DIN-rail mountable, rated up to 72 V DC and 15 A per channel, and fully compatible with standard automotive-type blade fuses.
AOSI DC Fuse Distribution Modules are available in screw-type and spring-type versions, with 4, 6, or 8 channels to meet different DC system requirements.
All models feature standard automotive blade fuses, LED indicators for each circuit, and DINレール取付 for easy installation.

All models share the same electrical rating (72V / 20A) and support wide wire range (0.5–6 mm² / 22–12 AWG). Differences mainly lie in channel count, dimensions, and connection type (screw or spring).
で AOSI Terminals, we understand that every DC control system demands precise circuit protection.With over 15 years of manufacturing experience, we provide a full range of DC fuse distribution modules — from compact 4-channel units to high-density 8-channel blocks, available in both screw and spring connection types.Every model is designed to deliver stable current flow, quick fault indication, and long-term reliability in automation and energy systems.
AOSI DC Fuse Distribution Modules are widely used across various DC power systems that require safe circuit protection そして 整理された配線.
Their compact structure, LED indication, and replaceable fuse design make them ideal for industrial and energy applications where uptime and reliability are critical.
In factory automation and machinery control cabinets, DC fuse modules provide reliable power splitting for PLCs, relays, and sensors.They simplify wiring and prevent total system shutdown when a fault occurs.
Used in solar combiner boxes or PV control units to protect individual strings and ensure stable output distribution.Each channel can be independently fused to isolate faults quickly.
In battery management and backup power systems, these modules handle DC output circuits safely and neatly.They enable maintenance-friendly layouts and protect valuable energy storage equipment.
Perfect for 12V / 24V on-board power distribution — including electric vehicles, boats, and mobile equipment —ensuring safety and easy access to each protected circuit.
Wiring a DC Fuse Distribution Module is simple and straightforward.
Each module includes one DC input terminal and multiple fused output channels that safely distribute power to different loads.
Step1. Connect the Power Input
Use the proper wire gauge (0.5–6 mm²) according to your current requirement.
Connect the positive (+) line from the DC power supply to the input terminal marked “IN” または “+”.
If available, connect the negative (–) line to the shared ground bus.
Ensure firm contact — tighten the screw or push in the wire depending on the terminal type.
Step2. Connect the Load Outputs
Each output channel corresponds to one fuse.
Connect each load device (such as PLC, relay, indicator light, or sensor) to an individual output terminal marked OUT1 / OUT2 / OUT3, etc.
This structure ensures that if one circuit fails, the others continue running safely.
📊 Wiring Diagram Example: The spring clamp will expand automatically once the screwdriver is pressed in.
Step3. Verify Fuse Ratings
Install standard automotive-type blade fuses (ATO/ATC) matching your circuit load.
Example: for a 10A circuit, use a 12A–15A fuse.
Always select fuses rated below your cable’s maximum current capacity.
Step4. Check LED Indicators
After power-up, the LEDs should remain off during normal operation.
If a fuse blows, the corresponding LED turns red, allowing quick fault localization.
