Hubbell Industrial Controls 69HAU3B Pressure Switch
The Hubbell Industrial Controls 69HAU3B Pressure Switch is a heavy-duty single-stage air compressor switch designed to manage system cycling with precision in industrial environments. Engineered with a NEMA 1 enclosure, this 2-pole pressure switch is rated for a 60 PSI factory setting, providing a reliable 15 PSI to 25 PSI differential range. The 69HAU3B features a 1/4" NPSC internal connection and is capable of handling up to 2 HP at 120V or 3 HP at 240V, making it a rugged solution for high-demand pneumatic applications. Contractors value this unit for its unloader valve, which prevents compressor motor startup under head pressure. This Hubbell 69H series switch is built with silver-cadmium oxide contacts for long-term conductivity and a robust diaphragm that withstands frequent cycling. For those replacing legacy Square D or Furnas pressure switches, this model offers a direct, technician-grade alternative that maintains consistent 60# air pressure thresholds without drifting during operation.
Key Benefits- Universal Compatibility: Fits most light to medium-duty air compressors requiring a 60 PSI operating point.
- Integrated Unloader Valve: Facilitates load-less starting to protect the motor and drive system from premature wear.
- Heavy-Duty Contact Blocks: Large, accessible screw terminals ensure secure wiring and reduced voltage drop.
- Durable NEMA 1 Housing: Protects internal components from debris while allowing easy access for field adjustments.
- Accurate Differential Control: Minimizes short-cycling by maintaining a consistent pressure gap between cut-in and cut-out.
What is the default cut-in and cut-out setting for the 69HAU3B?
This switch is factory-set for 60 PSI operation. While the differential is adjustable, it typically ships with a 15-25 PSI range suitable for standard industrial air reservoirs.
Is this switch suitable for use with water pumps?
No, the 69HAU3B is specifically designed for air compressor applications and includes an unloader valve. For water systems, use a dedicated pump switch without an unloader.
Can I adjust the pressure settings in the field?
Yes, the internal spring mechanism allows for fine-tuning the pressure range to meet specific site requirements, though it is optimized for 60# air pressure systems.
