SHACMAN X5000E SHACMAN M3000S SAHCMAN X5000E Chassis Central Fuse & Relay Box DZ93189712196
FUNCTION
1. Power Distribution Function: Safely and efficiently distributes the high-voltage and low-voltage electrical energy output by the power battery pack to the various electrical systems within the chassis-including the motor controller, DC-DC converter, electric power steering system, electric braking system, air suspension, lighting, sensors, and more.
2. Circuit Protection Function: Features multiple built-in high-capacity fuses that automatically blow in the event of a circuit overload, short circuit, or fault; this protects the wiring harness, controllers, and electrical components, thereby preventing electrical malfunctions from triggering fires or causing more extensive damage.
3. Relay Control Function: Integrates multiple high-current relays to enable remote on/off control of high-power devices-such as fans, oil pumps, water pumps, lighting, and preheating units-thereby enhancing both the safety and intelligence of the electrical system.
4. Signal Aggregation and Transmission: Consolidates various sensor signals and control commands from the chassis, transmitting them via the wiring harness to the Vehicle Control Unit (VCU) to facilitate fault diagnosis and comprehensive vehicle electrical management.
Working Principle
Inside the electrical box, power is distributed to multiple output circuits via copper busbars or heavy-gauge wire harnesses, supplying various chassis systems:
Motor Controller (MCU)
Electric Power Steering (EPS)
Electric Braking System (EBS/EPB)
Auxiliary components such as air suspension, cooling fans, oil pumps, and water pumps
Lighting, sensors, instrumentation signals, etc.
Advantages
| No. | Performance Advantage | Specific Description |
|---|---|---|
| 1 | High Integration | Integrates fuses, relays, power distribution, and signal interfaces into one compact box, simplifying wiring and greatly reducing harness complexity |
| 2 | Reliable Circuit Protection | Built-in multi-channel high-capacity fuses that quickly blow during overload or short circuit, effectively protecting key components such as motor controllers, steering systems, and braking systems |
| 3 | Strong Waterproof and Dustproof Performance | High protection rating enclosure (IP65 or higher), suitable for harsh conditions including rain, snow, mud, and dust on heavy-duty trucks |
Interfacing Relationships
It is mounted on the frame crossbeam of Shacman New Energy Delong pure electric heavy-duty trucks (models such as X5000E, M3000S, etc.), positioned in close proximity to the battery pack or motor controller to facilitate the centralized connection of high-voltage and low-voltage wiring harnesses.

Daily Maintenance Suggestions
| Maintenance Item | Maintenance Interval | Specific Content and Recommendations |
|---|---|---|
| Visual & Sealing Inspection | Daily / Weekly | Check the electrical box housing for cracks, deformation, rust, or aging of sealing strips to prevent water and dust ingress |
| Fuse Status Check | Weekly or every 2,000 km | Open the box cover and inspect fuses for blown, blackened, or loose conditions |
| Wiring & Connector Check | Weekly or every 2,000 km | Check all wiring harness connectors for looseness, oxidation, corrosion, or poor contact |
| Cleaning Maintenance | Weekly | Remove dust and oil from the surface and surrounding area of the electrical box to maintain good heat dissipation |
| Functional Abnormality Check | Daily (before operation) | After starting the vehicle, verify that chassis electrical systems (steering, braking, lights, fans, etc.) are working normally and no fault lights are on |
| Fastener Check | Monthly or every 5,000 km | Inspect the mounting bolts of the electrical box for looseness and retighten to specified torque if necessary |
