Antunes Controls 803113801 Pressure Switch

The Antunes Controls 803113801 is a professional-grade high gas pressure switch designed for critical monitoring in industrial combustion systems and commercial HVAC applications. As an HGP-D pressure switch, it provides high-accuracy supervision, breaking the electrical control circuit when gas pressure exceeds the manually adjusted setpoint between 5-28" WC. Built with a rugged die-cast aluminum housing, this unit is engineered for durability in demanding environments and can be mounted horizontally without requiring precise leveling, simplifying field installation for technicians.

This manual reset pressure switch features a DPDT (Double Pole Double Throw) electrical configuration, allowing for the independent control of two separate circuits across different voltages. For plumbing integration, it utilizes a standard 1/4" NPT connection for the gas inlet and a 1/8" NPT vent. It handles a maximum surge pressure of 10 PSI and is rated for ambient temperatures ranging from -40°F to 140°F. Reliance on Antunes 803113801 ensures compliance with safety interlock requirements for boilers, furnaces, and large-scale gas-fired equipment.

Key Benefits

• Dual-Circuit Versatility: The DPDT electrical switch allows for simultaneous signaling to a controller and a remote alarm or safety shut-off valve.
• Manual Reset Safety: Prevents automatic equipment restarts after a high-pressure trip, ensuring a technician inspects the system before resuming operation.
• Flexible Mounting: The industrial gas pressure switch design allows horizontal mounting, reducing labor time during tight-space retrofits.
• Wide Operating Range: Adjustable 5-28 inch water column range covers a broad spectrum of commercial burner and boiler specifications.

Common Questions

How do I reset the Antunes 803113801 after a trip?
Once gas pressure has dropped below the setpoint, physically depress the reset lever located on the housing. The switch will not reset automatically even if pressure returns to normal levels.

Can this switch be used for low gas pressure applications?
No, the 803113801 HGP-D is specifically a high gas pressure switch that trips on rising pressure. For low-pressure monitoring, an LGP-D series switch should be utilized.

What is the maximum surge pressure the diaphragm can handle?
The unit is rated for a maximum surge pressure of 10 PSI. Exceeding this limit may damage the internal diaphragm and affect calibration accuracy.
