Hubbell Industrial Controls 69HA3 Pressure Switch
The Hubbell Industrial Controls 69HA3 Pressure Switch is a heavy-duty, industrial-grade control designed for precision monitoring in commercial air compressor and HVACR systems. This 69H Series switch excels in demanding environments where reliable pressure regulation is non-negotiable. It features an adjustable range of 15-60 PSI and a configurable differential of 7-15 PSI, allowing technicians to fine-tune the cut-in and cut-out points to specific system requirements. Built with a rugged, painted steel case, the 69HA3 is engineered to withstand the vibration and harsh conditions of mechanical rooms. The internal mechanism includes visible contacts and straight-through wiring with two large ground screws, significantly reducing installation time for contractors. The 3/8" female NPT connection ensures a secure fit, while the 100% copper contacts provide high electrical conductivity for single-phase or three-phase applications up to 5 HP. This pressure differential switch is a standard solution for maintaining system equilibrium and preventing equipment overpressure.
Key Benefits- Industrial Durability: The sturdy steel enclosure and NEMA 1 rating protect internal components from moisture and debris common in heavy-duty compressor environments.
- Precision Calibration: Features a no-drift pressure setting mechanism with simple screw adjustments for accurate pressure differential control.
- Contractor-Friendly Design: Ample wiring room and a clear contact layout simplify field diagnostics and integration into existing motor control circuits.
- Versatile Compatibility: Rated for both 115V (2HP) and 230V (3HP/5HP) motors, making it a universal choice for diverse industrial process control needs.
How do I adjust the cut-in and cut-out settings on the 69HA3?
Using Screw A, turn clockwise to increase both the cut-in and cut-out pressures. For the differential, Screw B adjusts the cut-out point independently; turning it clockwise increases the gap between the two thresholds.
Can this switch be used for water pump applications?
While primary applications include air compressors and HVAC systems, the Hubbell 69HA3 is UL listed and CSA certified for fluid and gas monitoring, provided the 15-60 PSI range meets the pump's head pressure requirements.
Does this model include an unloader valve?
The standard 69HA3 does not include a factory-installed unloader valve. If your application requires a compressor head pressure release, look for the 69HAU3 variant which features the integrated unloader.
