Product Description of the SiBo Fuse Box (12V Power Distributor)
The SiBo Fuse Box is an innovative 6-way power distribution solution specifically designed for use in vehicles. With 5 A protection per output at 12 V, it offers a reliable and safe way to supply power to multiple electrical consumers in automotive applications.
The outputs are activated when either the “Terminal 15” input or the “external power supply” (V-Extern) signal is present.
When the ignition is on (Terminal 15 active), all outputs are enabled. Red LEDs indicate when the load limit is reached. In the event of overcurrent, the affected output is automatically disabled, and the associated LED remains on. An output that has been switched off is automatically reactivated as soon as the overload condition is no longer present.
- Current consumption in idle state: 30 mA
- With relay: max. 100 mA (no load on outputs)
- In off state: < 1 mA

Use Cases in Automotive Applications
1. Lighting Systems
The SiBo Fuse Box is ideal for supplying additional lighting systems, such as LED headlights, interior lighting, or underbody lights. It enables easy installation when multiple circuits need to be protected separately and ensures even power distribution.
2. Accessories and Add-on Devices
Whether coolers, chargers, or radios – the SiBo Fuse Box allows various accessories to be operated safely and efficiently without requiring additional fuses.
Comparison: SiBo Fuse Box vs. Conventional Fuse
| Feature | SiBo Fuse Box | Conventional Fuse |
|---|---|---|
| Flexibility in power distribution | Provides up to six individually fused outputs | Requires one fuse holder per circuit |
| Ease of installation and use | Simple installation with ignition or external power control | Complex setup to implement switching conditions |
| Overload protection and indication | Integrated LEDs indicate overload, automatic reset | Fuse may blow, no visual feedback |
| Quick reset | Automatic reset once overload condition is cleared | Manual replacement of blown fuse |
