A.J. Antunes 8024202041 Pressure Switch

The Antunes 8024202041 is a robust air differential pressure switch engineered for precise monitoring in demanding HVAC and commercial combustion systems. This model JD-2 switch features a field-adjustable set point range of .17" to 1" W.C., providing critical safety interlocking for low-pressure applications. Constructed with a durable aluminum die-cast housing, the unit utilizes a single pole double throw (SPDT) switch configuration, allowing for versatile wiring in normally open or normally closed circuits. For pneumatic integration, it is equipped with a 1/4" male NPT bottom connection and a 1/8" female NPT side connection. This pressure switch is FM approved and UL listed, ensuring compliance with strict industrial safety standards. It is designed to sense air pressure, vacuum, or differential pressure, making it an essential component for proving airflow in blower systems or monitoring filter status in air handling units.

• Precise Calibration: The adjustable set point allows technicians to fine-tune the .17-1"wc range to meet specific site requirements.
• Rugged Construction: Built with a die-cast aluminum housing to withstand the vibrations and temperature fluctuations common in mechanical rooms.
• Flexible Mounting: Dual NPT porting options (1/4" male and 1/8" female) facilitate easy retrofitting into existing Antunes pressure switch 8024202041 configurations.
• Safety Certified: FM approval ensures the device meets rigorous standards for loss prevention and reliability in combustion air applications.

Commonly Asked Questions

How do you adjust the trip point on the Antunes JD-2 switch?
Remove the top cover to access the adjustment screw. Turning the screw clockwise increases the set point, while counter-clockwise decreases it. Always use a calibrated manometer to verify the air pressure switch settings during commissioning.

What are the electrical ratings for this SPDT switch?
The Antunes 8024202041 is typically rated for 10A to 15A at 125/250/480 VAC, depending on the specific application load. Always verify the amperage draw of your controller or relay before landing wires.

Can this switch be used for sensing vacuum?
Yes, by utilizing the 1/8" NPT side port and leaving the 1/4" NPT port open to atmosphere, the JD-2 pressure switch can effectively monitor vacuum levels in the specified range.
