Hubbell Industrial Controls 69HAU3Z2935 Pressure Switch
The Hubbell Industrial Controls 69HAU3Z2935 Pressure Switch is a heavy-duty solution engineered for precise air compressor pressure control in industrial and commercial environments. This 69H Series model is specifically designed for high-demand pneumatic systems requiring a reliable compressor cut-out switch with integrated protection features. Featuring a 29–35 PSI operating range and a maximum cut-out pressure of 65 PSI, it ensures accurate cycling for low-pressure applications like climate control or specific process automation.
Built with veteran contractors in mind, this industrial pressure switch features visible 2-pole, double-break contacts for straightforward inspection and straight-through wiring to reduce installation time on the job site. The unit is equipped with a high-quality unloader valve, which bleeds head pressure from the pump to ensure smooth, load-free restarts, extending the life of the motor. Its rugged, corrosion-resistant cover and NEMA 1 enclosure provide durability in standard indoor shop environments, while the 3/8" female NPT connection offers a secure fit for standard manifold configurations.
Key Benefits
- Enhanced System Protection: The built-in unloader valve prevents high-torque restarts by discharging residual air pressure in the pump head.
- Industrial-Grade Durability: Constructed with a corrosion-resistant non-metallic cover and high-strength 2-pole contacts for long-cycle life.
- No-Drift Reliability: Internal mechanisms are designed for no-drift pressure settings, maintaining consistent cut-in and cut-out points without frequent recalibration.
- Simplified Maintenance: Visible contacts allow technicians to quickly diagnose electrical wear without complex disassembly.
- Certified Safety: Fully UL Listed and CSA Certified to meet strict job site compliance and safety standards.
Common Questions
What is the purpose of the unloader valve on this Hubbell switch?
The unloader valve is a critical safety and performance component. When the compressor reaches its cut-out pressure (65 PSI max), the valve opens to release trapped air between the pump and the check valve. This allows the motor to start without fighting backpressure during the next cycle.
Can the pressure settings be adjusted on the 69HAU3Z2935?
Yes, while this model comes factory-set for a 29–35 PSI range, the 69H Series allows for field adjustments. However, it is optimized for applications where 65 PSI is the absolute maximum cut-out threshold.
Is this switch compatible with 3-phase motors?
This pressure switch is a 2-pole, double-break design typically used for single-phase motor control. For 3-phase applications, it is commonly used as a pilot device to trigger a magnetic starter.
