Sinotruk HOWO
| Attribute | Description |
|---|---|
| Part Name | 7-Way Fuse Device Assembly / 7-Circuit Fuse Box / Multi-Circuit Fuse Holder |
| Common Names | Fuse Block, Fuse Panel, Electrical Distribution Module, 7-Way Fuse Holder |
| OE Number (Original Equipment) | WG9720580050 |
| Manufacturer | China National Heavy Duty Truck Group (Sinotruk / CNHTC) |
| Function | Distributes 24V DC power from the main battery circuit to multiple auxiliary systems and provides overcurrent protection via individual fuse slots |
| Mounting Location | Installed in the driver’s cab (near dashboard), engine compartment, or chassis-side electrical junction area |
| Design Type | Modular plastic enclosure with integrated fuse holders and terminal connections |
Name1
Name2
| Parameter | Specification |
|---|---|
| Rated Voltage | 24V DC – Standard for commercial heavy vehicles |
| Number of Circuits | 7 independent fuse-protected channels |
| Per-Circuit Current Rating | Supports fuses from 10A to 30A depending on application (e.g., lighting, ECU, wipers, instruments) |
| Housing Material | Flame-retardant engineering plastic — typically PA66 (Nylon 66) or ABS, UL94 V-0 rated |
| Contact Material | Tin-plated brass or copper alloy terminals for high conductivity and corrosion resistance |
| Insulation Strength | High dielectric strength (>500V AC) ensures safe isolation between circuits |
| Operating Temperature Range | -40°C to +120°C (-40°F to +248°F) |
| Storage Temperature | Up to +150°C (short-term heat resistance) |
| Weight | Approx. 0.15 – 0.3 kg |
| Dimensions (Approx.) | 12 cm × 6 cm × 4 cm |
| Protection Level | IP54 – Dust protected and splash resistant (when cover is closed) |
| Compliance Standards | Meets ISO 9001, CCC (China Compulsory Certification), GB/T standards for automotive electric |
⚠️ WARNING: Work involves live electrical circuits. Always disconnect battery before servicing.
Park securely and apply parking brake.
Disconnect both battery terminals (start with negative).
Wait 2 minutes for residual voltage to dissipate.
Locate the 7-way fuse device (usually under dash or near steering column).
Remove protective cover carefully.
Take photo of existing wiring for reference.
Identify input cable (from main power source or master relay).
Loosen terminal screws and remove wires.
Inspect for signs of overheating or corrosion.
Unscrew mounting brackets or release clips.
Gently pull out the old fuse block — avoid damaging connected wires.
Position new unit into place.
Secure with original hardware — torque to ~6–8 N·m.
Reconnect main power supply to input terminal.
Attach output wires to correct fuse positions according to original routing.
Replace each fuse with the exact amperage rating specified on the lid or vehicle manual:
Example: 10A, 15A, 20A, 30A
Never use higher-rated fuse or jumper wire!
Close and secure the protective cover.
Reconnect battery.
Turn ignition ON and test all protected systems:
Lights
Wipers
Horn
Gauges
Confirm no smoke, heat, or burning smell.
