Hubbell Industrial Controls 69HAU2 Pressure Switch
The Hubbell Industrial Controls 69HAU2 is a heavy-duty single-stage pressure switch designed for reliable performance in commercial air compressor applications. Engineered for demanding industrial environments, this switch features a factory preset of 100 PSI cut-in and 125 PSI cut-out, with an adjustable range of 20 to 35 PSI to fine-tune system pressure requirements. The 69HAU2 series is built with a unloader valve to prevent motor startup under load and a 1/4" NPT female connection for straightforward mechanical integration. Its robust contact design ensures long-term electrical reliability under high-cycling conditions, making it a standard replacement for Class 69HAU series controls. Contractors favor this individual pressure switch for its durable construction and consistent differential pressure control, ensuring the pneumatic system maintains optimal operating parameters without frequent calibration drift.
Key Technical Benefits- Heavy-Duty Contact Block: Designed for high-amperage single-phase power or pilot duty applications.
- Integrated Unloader Valve: Facilitates easy compressor motor starts by venting head pressure during the off-cycle.
- Corrosion-Resistant Housing: Built to withstand harsh mechanical rooms and moisture-heavy environments.
- Field-Adjustable Differential: Allows technicians to customize the cut-in and cut-out points within a 20-35 PSI spread.
- Standard Fitting: Equipped with a 1/4" NPT internal thread for universal mounting on most receiver tanks.
How do I adjust the pressure settings on a 69HAU2?
Adjustments are made via the internal range nut. Turning the nut clockwise increases both the cut-in and cut-out pressure while maintaining the preset differential spread.
What is the maximum amperage rating for this switch?
The Hubbell 69HAU2 is typically rated for up to 2HP at 120V or 3HP at 240V in single-phase applications, though verifying the motor’s FLA against the nameplate is recommended.
Can this pressure switch be used for water pump applications?
While functionally similar, the 69HAU2 includes a mechanical unloader valve specifically designed for air compressors; for water systems, a switch without an unloader is usually preferred.
