4Fuse (spare)Flat-blade type2

The 200 A and 100 A positions are high-current contactors for the chassis-side master-switch and pre-heat duty. Exact part numbers follow the programme BOM.

Built-in load functions

The reference build covers these 5 functions:

  • Master-switch control
  • Pre-heat control
  • Starting control
  • Battery protection
  • Alternator protection

Choosing the NBX‑969: chassis distribution, body-cavity PDB, or a configurable sealed box

IP54 covers dust and splashing water, not water jets or immersion. For a body-cavity central PDB, see NBX‑957.

NBX‑968 is the same IP54. Its contents are quoted per program. NBX‑969 is the chassis distribution box with the reference build above. Drawings via the contact page.
