Hubbell Industrial Controls 69JF8Y Pressure Switch

The Hubbell Industrial Controls 69JF8Y Pressure Switch is a heavy-duty, field-adjustable control designed for demanding air compressor and water system applications. Engineered as part of the versatile 69J Series, this switch is a direct replacement for the 69MB8Y and features high-performance Silver Cad-Oxide brazed contacts to ensure efficient electrical conduction and extended cycle life. It is factory-set for a 115-150 PSI range but offers a broad minimum cut-in pressure of 90 PSI and a maximum cut-out pressure of 165 PSI. This unit is specifically built with an integrated unloader valve?essential for relieving head pressure and preventing the motor from starting under load. The unloader is designed for maximum flexibility, allowing for 8-position rotation to simplify tubing runs. With a standard 1/4" Female NPT connection and robust NEMA 1 enclosure, the Hubbell 69JF8Y provides reliable performance for 1.5 HP to 3 HP industrial motors.

Key Benefits for Technicians:

• Broad HP Compatibility: Rated for 1 Phase 120V (1.5 HP), 1 Phase 240V (2 HP), and 3 Phase 240V (3 HP) systems.
• Optimized Unloader Valve: Features an improved adjustable unloader that can be rotated to accommodate various compressor configurations and reduce assembly time.
• Industrial Grade Materials: Equipped with silver cad-oxide contacts for superior resistance to arcing and pitting in high-cycle environments.
• Standard Connection: Utilizes a 1/4-inch Female NPT inlet for easy integration into existing pneumatic or hydraulic manifolds.
• Certified Reliability: UL listed, CSA certified, and CE approved for global industrial compliance.

Common Questions & Answers:

Does the 69JF8Y include a manual disconnect lever?
No, this specific model (69JF8Y) does not feature an Auto-Off disconnect lever. If your application requires a manual shut-off at the switch, please consult our technical team for the "L" designated version of the 69J series.

Can I adjust the factory pressure settings?
Yes. While pre-set at 115-150 PSI, the 69JF8Y pressure switch is field-adjustable between a 90 PSI minimum cut-in and a 165 PSI maximum cut-out with a 25-38 PSI differential range.

Why is my unloader valve leaking after the compressor stops?
If air continuously escapes from the unloader after the unit reaches cut-out, the issue is typically a failing tank check valve rather than the pressure switch. The unloader is functioning correctly by attempting to bleed the head pressure.
