ABB P4LQA (HENF209736R0003) – Panel‑mount Industrial Control Accessory for Reliable Operator Stations

The ABB P4LQA, referenced by part number HENF209736R0003, is supplied as an original ABB accessory within the P4 family for low‑voltage control panels. From my experience, it’s typically selected when you need a like‑for‑like replacement in an operator panel or to complete a new panel build where consistency with existing ABB hardware matters. You might notice that maintenance teams favor it because it swaps in cleanly with minimal adjustment, helping keep downtime tight.

Technical Specifications

Application Fields

You’ll typically see this part used in:

• OEM operator panels and control stations where ABB P4 assemblies are standard
• Plant MRO replacements on conveyor, packaging, or material handling lines
• Utilities and process industries aiming to keep ABB control hardware uniform across sites
• Panel upgrades where compatibility with existing ABB contact blocks or actuators is required

Advantages & Value

• Reliability – Genuine ABB sourcing helps avoid fit issues that sometimes appear with look‑alike parts.
• Compatibility – Seems to be designed to sit neatly within ABB P4 assemblies, reducing trial‑and‑error during maintenance.
• Downtime reduction – Quick swap for worn components; typically no rewiring since it’s a mechanical accessory.
• Procurement simplicity – Clear traceability via HENF209736R0003, making cross‑site stocking straightforward.

A maintenance supervisor at a dairy plant told us the swap took under 20 minutes, mainly because mounting points lined up exactly with their existing ABB panel hardware—small detail, big time saver.

Installation & Maintenance

• Environment – Install in a clean, dry control cabinet or operator station with adequate ventilation; avoid direct oil spray or abrasive dust where possible.
• Panel prep – De‑energize the panel, apply lockout/tagout, and follow ABB panel cutout and fastening recommendations for the P4 family.
• Wiring – Not applicable for this accessory; verify adjacent devices (contact blocks, lamps) are correctly seated and strain‑relieved.
• Safety – Confirm proper grounding of the panel assembly, correct torque on fasteners, and no interference with door seals or other operators.
• Routine checks – Periodically inspect for loosening due to vibration, clean dust with a dry lint‑free cloth, and verify gaskets/labels are intact.

Quality & Certifications

• Manufactured under ABB quality systems (typically ISO 9001)
• Compliance: CE and RoHS in most cases for ABB low‑voltage components (final conformity per part label/datasheet)
• Manufacturer warranty: ABB policies vary by product family; commonly 12 months (verify for your exact build)
• Our warranty support: 365 days
