Hubbell Industrial Controls 69HAU1 Pressure Switch

The Hubbell Industrial Controls 69HAU1 Pressure Switch is a heavy-duty solution for commercial and industrial air system regulation. Built for the rigorous demands of larger compressors and HVACR applications, this dual-pole pressure switch features a sturdy painted steel cover and case to withstand harsh shop and mechanical room environments. Professionally pre-set at 115-150 PSI, the 69HAU1 provides a broad 40 PSI cut-in and 250 PSI cut-out maximum limit, with an adjustable differential range of 35-50 PSI to fine-tune cycling performance. This model comes integrated with a right-side unloader valve for 1/4" tubing, ensuring the compressor starts without backpressure. Rated for up to 5 HP, it utilizes a 3/8" female NPT bottom connection and straight-through wiring with visible contacts for simplified field installation and troubleshooting. Whether you are servicing climate control systems or high-demand heavy-duty air compressors, this switch offers the reliable "no-drift" settings required for consistent system pressure management.

Key Benefits:

• Industrial Durability: Rugged painted steel construction provides superior protection over standard plastic-housed switches.
• Integrated Unloader: Includes a factory-installed unloader valve to prevent motor strain during start-up cycles.
• Adjustable Range: Flexible 35-50 PSI differential allowing for precise system calibration between cut-in and cut-out.
• High Compatibility: Direct replacement for many Furnas and Hubbell 69H series models used in fire suppression and HVAC.

Common Questions:

What is the maximum pressure rating for the 69HAU1?
While the factory setting is 115-150 PSI, the 69H series is designed for a maximum open cut-out of 250 PSI, making it suitable for high-pressure industrial air systems.

Does this switch support three-phase power?
Yes, the Hubbell 69HAU1 is rated for both single-phase and three-phase applications, handling up to 5 HP on 230V systems.

Can I adjust the cut-in and cut-out points independently?
The switch uses two adjustment screws: one to shift the entire pressure range and another to adjust the cut-out differential, ensuring you can meet specific system requirements.
