Description:

In a fuel cell system, the low-voltage components such as the stack, air compressor, cooling system, DC/DC converter, pre-charge box and controller all require a stable low-voltage power supply. The traditional solution uses the vehicle key switch for distributed low-voltage power distribution, which has problems such as complex wiring, insufficient protection and difficult troubleshooting. The fuse box (low-voltage distribution box) is precisely a key electrical component designed to solve this problem - it integrates low-voltage power distribution, over-current protection and relay control functions, providing centralized, safe and reliable power distribution for each component of the fuel cell system.

This fuse box integrates 26 fuses and 8 relays; each power distribution branch includes a series-connected fuse and relay, the fuse for over-current protection and the relay for power on/off control. When the current of a branch exceeds the rated value, the fuse blows and cuts off the circuit, preventing the harness from overheating or the component from being damaged; the relay is driven by the system controller to realize the timing control and safe on/off of each branch.

The housing uses PA6+GF15 material (nylon + glass fiber), with excellent mechanical strength, high temperature resistance and flame retardant properties. The interior includes a conductive plate, upper cover, lower cover and clips of various specifications (used to fix fuses and relays of different models); the clip models include MINI fuse clip (1406503/1406504), MICRO relay clip (1406506), JCASE clip (1406507), etc. The product dimensions are 189x105x102mm, with a compact structure, convenient for installation in the engine compartment or the cab.

Q3: Is there a minimum order quantity (MOQ) limit?
A: There is no strict MOQ limit; 10-piece sample trial orders are supported, and bulk order prices are more favorable.

Q4: Why does a fuel cell system need a fuse box (low-voltage distribution box)?
A: Each low-voltage component of a fuel cell system (stack, cooling system, DC/DC, pre-charge box, controller, etc.) requires a stable low-voltage power supply. Traditional distributed power supply has problems such as complex wiring, insufficient protection and difficult troubleshooting. The fuse box integrates low-voltage power distribution, over-current protection and relay control, providing centralized, safe and reliable power distribution for each component.

Q5: How many fuse and relay circuits does the fuse box support?
A: It supports 26 fuses and 8 relays; each power distribution branch includes a series-connected fuse and relay.

Q6: What is the working temperature range of the fuse box?
A: The working temperature range is -40C~125C, meeting harsh vehicle environment requirements.

Q7: What are the installation requirements of the fuse box?
A: The mounting hole spacing is 166x100mm, mounting hole Phi8mm; it can be fixed to the system surroundings or in the engine compartment with bolts. During installation, ensure reliable harness connection and avoid connector loosening.

Q8: How to handle product failures?
A: We implement a strict quality control system, with an out-of-factory defect rate below 0.2%. During the warranty period, small batches of defective products will be replaced with new ones in the next order; batch quality problems will be negotiated for repair or replacement to ensure customer rights.
