Description
ABB O3EGb (HENF315118R2) – Original ABB operator/selector component for control panels and machinery
The ABB O3EGb, referenced by manufacturer code HENF315118R2, is an original ABB spare designed for dependable panel operation and selector duties. From my experience, this part is typically used as a robust operator element or selector in control cabinets—ideal for start/stop, mode selection, or isolating low-voltage control circuits in machinery and process lines. If you’re replacing a worn operator or standardizing parts across multiple panels, this model helps you keep everything OEM and consistent.

Application Fields
You might notice that O-series operator components like the O3EGb show up anywhere reliable manual control is needed. Typical use cases include:
- Machine tools and packaging lines (mode selection, enabling/disabling subsystems)
- Material handling and conveyors (maintenance/override selectors)
- Process skids and pump panels (local/remote or auto/manual switching)
- Power/control distribution cabinets (isolation/selection of control circuits)
A maintenance supervisor told us they swapped in the O3EGb during a scheduled stop and the panel was back online in minutes—no programming changes, just straight mechanical fit and wiring.
Advantages & Value
- Reliability: Feels solid in daily operation; built for industrial duty cycles.
- Compatibility: OEM fit with ABB panels and accessories reduces retrofit effort.
- Downtime savings: Mechanical part; quick changeover, no firmware to align.
- Support: We provide documentation support tied to HENF315118R2 and assist with equivalent configurations if your panel variant differs.
Installation & Maintenance
- Environment: Install in a clean, dry control cabinet; allow ventilation and avoid direct vibration hotspots when possible.
- Mounting: Panel-mount per ABB guidance; ensure correct orientation and secure tightening torque on the operator and contact blocks.
- Wiring: Use appropriately rated ferrules; separate control and power wiring; confirm NO/NC mapping before energizing.
- Safety: Isolate power and lock-out/tag-out prior to work; verify absence of voltage.
- Routine checks: Periodically inspect mechanical action, terminal tightness, and panel gasket integrity; clean dust/debris from the operator area.
- Updates: No firmware. If contact configuration changes are needed, select the appropriate ABB contact blocks to match your wiring diagram.
Quality & Certifications
ABB operator components like this typically carry CE conformity and, in many cases, cULus and RoHS compliance for major markets. Certification specifics can vary with the exact configuration, so we can provide the datasheet and CoC upon request. Manufacturer policies usually include standard quality assurance; we back this unit with a 365-day warranty for added peace of mind.
Related/Supporting Components
- ABB auxiliary contact blocks (NO/NC) for custom contact arrangements
- Panel sealing gaskets and legend plates (to reach typical IP ratings and clear labeling)
- Terminal blocks and ferrules sized to your control voltage and current
Note: The O3EGb designation and manufacturer code HENF315118R2 identify the exact ABB variant. If your cabinet uses a different cam position or contact layout, share a photo of the nameplate or wiring diagram and we’ll match the right configuration.
