H8351ABAAAB is a Bulgin indicator/holder.
2. Part-number decode
- Series: Bulgin H83x
- Type: indicator/holder
3. Compatibility & ordering
Bulgin makes rugged anti-vandal pushbuttons (the Vandal-Resistant/Buccaneer line), sealed connectors, and indicators for harsh environments. Match by type, actuation, illumination, sealing, and mounting, then use the manufacturer datasheet to confirm the exact contact and termination encoded in the part number.
4. Data-quality note
The Bulgin product line/type is identified; the detailed configuration is left to the datasheet rather than guessed. Flagged decoded-partial.

安装快速参考
Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).
Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

故障排除
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
