Mechanical layout
Mating connector
The standard NBX-968 build uses a single TE 281810-1 sealed harness connector. Wire-side seals, terminal P/N and pin-out are confirmed against the customer harness drawing at quotation.
Fuse & relay configuration
Standard build, customised on a programme basis:
| # | Component | Spec | Qty |
|---|---|---|---|
| 1 | Main contactor | 200 A | 3 |
| 2 | Relay | ISO type | 4 |
| 3 | Fuse | Flat-blade MAXI | 5 |
| 4 | Fuse | Flat-blade MIDI | 6 |
| 5 | Fuse | ATO/ATC blade | 12 |
| 6 | Function customisation | Per circuit-diagram changes | — |
The 200 A positions are high-current main contactors for master-switch and pre-heat duty; the ISO-type positions take standard automotive relays for control-side switching. Exact part numbers follow the programme BOM.
Built-in load functions
Programme-specific load mix — the NBX-968 reference build covers the following 8 engine and start-system functions:
- Master-switch control
- Pre-heat control
- Starting control
- Battery protection
- Alternator protection
- Start cut-off control
- Engine excitation protection
- Engine charging protection
Manufacturing & testing
Manufactured under IATF 16949. IP testing follows IEC 60529 in our in-house environmental lab.
Related models & how to ask
The NBX‑969 chassis distribution box is the same IP54, with a defined power-management set rather than contents quoted per program. This rating does not cover water jets or immersion. For a water-jet position, the NBX‑961 and the NBX‑971 are both IP65; NBX‑961 has a CAN harness pin-out, and NBX‑971 does not. If the point only needs passive terminal joining with no fuses or relays inside, see the NBX‑965 sealed junction box (IP65). For an earth bond, see the NBX‑966 earth bonding plate (IP5X).
