Hubbell Industrial Controls 69HAU3 Pressure Switch
The Hubbell Industrial Controls 69HAU3 Pressure Switch is a heavy-duty, Furnas-style air compressor switch engineered for demanding commercial and industrial applications, including climate control systems and fire suppression. This rugged 69H Series controller is factory-set at 30-40 PSI but offers a broad adjustment range with a minimum close cut-in of 15 PSI and a maximum open cut-out of 60 PSI. Built with a sturdy painted steel case and cover, it withstands harsh mechanical room environments while maintaining no-drift pressure settings via its 2-pole, double-break visible contacts.
Designed for maximum versatility, the 69HAU3 includes a pre-installed unloader valve to facilitate load-free compressor restarts, improving motor longevity. It features a 3/8 inch Female NPT connection and a large diaphragm for precision at low-pressure thresholds. This heavy-duty pressure switch supports motor ratings up to 2 HP at 120V and 5 HP on three-phase applications, making it a reliable choice for HVAC compressor repair and industrial air system maintenance. Straight-through wiring and ample internal room ensure a fast, professional installation for any HVAC technician.
Key Benefits- Heavy-Duty Construction: Features a rugged steel housing and corrosion-resistant cover for long-term durability in industrial settings.
- Integrated Unloader Valve: Prevents the compressor from starting under load, protecting the motor and reducing electrical inrush.
- Precise Pressure Control: High-performance diaphragm ensures accurate pressure switch adjustment within an adjustable 7-15 PSI differential.
- Broad Compatibility: Rated for both single and three-phase systems; can be paired with a magnetic starter for larger horsepower requirements.
- Service-Friendly Design: Visible contacts and straight-through wiring simplify diagnostic checks and field replacements.
What is the default factory setting for this switch?
The 69HAU3 is factory-calibrated for a 30 PSI cut-in and 40 PSI cut-out, though it can be field-adjusted using the internal range and differential screws.
Can I use this switch if my system does not require an unloader valve?
Yes. If an unloader is not needed for your specific setup, you can simply leave the valve port unconnected without affecting the switch’s pressure sensing performance.
Is this switch suitable for high-pressure industrial compressors?
While the 69H series can handle up to 250 PSI, this specific 69HAU3 model is optimized for lower-pressure ranges with a maximum cut-out of 60 PSI, typically found in climate control and specialized air systems.
