Description
ABB G3ESa (HENF318736R1) – Original spare module for ABB automation cabinets
The ABB G3ESa, identified by part number HENF318736R1, is an original ABB board-level module used as a like-for-like replacement inside ABB control/robotics cabinets. From my experience, this part is typically selected when a plant needs a fast, zero-modification swap to restore a controller back to service. One thing I appreciate is the traceable HENF code on the label—it makes cross-checking with existing BOMs and service records straightforward. In many cases, maintenance teams install it as a drop-in, power up, and the system recognizes it without re-wiring.

Application Fields
You’ll typically see the G3ESa used in ABB automation systems where stable, OEM-certified modules are required—robotic cells, discrete manufacturing lines, and motion/drive control cabinets. One maintenance supervisor told us they keep one in stock for their robot weld cells, “because every hour saved on troubleshooting is worth a shift of production.”
Advantages & Value for Procurement
- Lower downtime risk – Genuine, revision-matched part reduces integration uncertainty.
- Cost control – Predictable replacement without engineering changes or re-cabling.
- Compatibility assurance – Same mechanical and electrical interface as the original module.
- Traceability – HENF318736R1 coding supports compliance and audit trails.
- Technical support – Guidance on part identification and installation steps if you need a quick sanity check before shutdown.
Installation & Maintenance
- Power down and lockout/tagout the cabinet; wait for DC bus discharge where applicable.
- Use ESD wrist strap and ESD mat; handle the board by edges only.
- Verify the part label: ABB G3ESa, HENF318736R1; match against your controller’s spare list.
- Seat the module evenly; confirm that board-edge connectors are fully engaged before tightening retainers.
- After replacement, perform a controlled startup; check system diagnostics for normal recognition.
- Routine care: keep cabinet air filters clean, maintain ambient 0–45 °C, inspect connectors during scheduled shutdowns.
- Firmware/parameters: if your plant procedure requires, back up controller data before swap; restore as needed.
Quality & Certifications
- Manufacturer quality systems typically aligned with ISO 9001
- CE and RoHS conformity applicable to ABB industrial control modules
- 365‑day warranty from delivery date
If you’re replacing an installed unit, you might notice the fastest path is to share your controller type and any revision letters on the old label—we’ll confirm form, fit, and function before you schedule the shutdown.
