- Complete GE part number 531X305NTBANG1 with NG1 suffix.
- NTB/3TB terminal-board role in a legacy control assembly.
- Exact terminal, jumper and plug mapping required for replacement.
The board is an interface boundary, so wiring evidence is as important as the printed part number.
Closely related 531X variants may share a layout while carrying different termination assignments.
Receiving should compare the suffix and board details with the removed assembly before site release.
