Renaming our wiring on-board power distributors

On-board power distributors are ready-to-connect power distributors that ensure the safe sub-distribution of single-phase AC voltage networks in vehicles. From now on, at LEAB the most important information about the various functions will be contained in the product name. 

After all, our wiring harnesses differ in many areas. The decisive factor for choosing the right product is ultimately how well the form and functions fit your desired application. The following information is required:

  • Housing: PCM3=AK03, PCM5=AK05, PCM9=AK09 or PCM12=AK12

  • Function: NVS - mains priority circuit, SV - start prevention, ZA - additional output, HK - auxiliary contact, ZU - time changeover, ESB - inrush current limiter or PEN - PEN bridge.

  • Input connection: K=Cable bushing, N=Neutrik, or D=DEFA

  • Output connection: K=Cable bushing, N=Neutrik, or D=DEFA

  • R – Relay

  • RCD or ISO monitor

  • Fuse: 10 A or 16 A

From now on, all these questions can be answered simply by taking a look at our products. Because the answers are contained in the new names of our wiring harness distributors.

At a glance: This diagram shows the naming system.

To what convention are the wiring on-board power distributors being renamed?

Example: PCM5-PEN-1N-1N-1R-1RCD-10

  1. PCM5: The first part describes the enclosure size based on the available part units. 

  2. PEN: The second part describes the function of the wiring system distributor. For example, PEN stands for PEN bridge. 

  3. 1N: The type and number of connections for the input are shown here. In this case 1x Neutrik.

  4. 1N: The type and number of connections for the output are shown here. In this case 1x Neutrik.

  5. 1R: A relay is installed. The number of pieces is shown at the beginning.

  6. 1RCD: Here you can read whether RCD or ISO monitors are present. In our example RCDs are used.

  7. Finally: How many amps does the fuse have? In this case 10 A.

Once you have internalised this, you will soon be able to see at a glance the properties of our various wiring distributors and determine which one is right for you.
