Overview
The NBX-954 serves the same body and accessory circuits as the NBX-952; a separate body controller makes the switching decisions.

How it differs from NBX-952 and NBX-972
The three boxes sit on the same Power Distribution shelf but solve different problems. Pick the one that matches the program's level of control logic and circuit count:
| Model | Role | On-board logic | Sealing | Fused circuits | Best for |
|---|---|---|---|---|---|
| NBX-954 | Passive central distribution | Passive | IP65 | 31 (26 ATO + 5 spare) | Programs with separate BCM, mid-density body wiring |
| NBX-952 | Centralized PDB + body control logic | CAN bus | IP65 | 2 box + 28 mini, 7 spare | Programs that want one box for distribution and body-circuit logic |
| NBX-972 | High-density passive central PDB | Passive | IP4X vented | ~65 (mini + J-case) | Heavy truck / construction with high circuit count & aftertreatment functions |
For the architectural decision between a junction box, a fuse box and a relay-fuse distribution box, see the junction vs fuse vs relay box guide.
Manufacturing & testing
Built under IATF 16949 with APQP project planning and a PPAP package available for OEM programs. End-of-line functional test on every unit (relay actuation and fuse-circuit continuity) before packaging; environmental validation and EMC pre-compliance screening in our in-house lab when the program requires it.
