Antunes Controls 803114001 Gas Switch

The Antunes Controls 803114001 Gas Switch is a high-performance RHGP-D pressure switch designed for critical monitoring in industrial burner systems and commercial HVACR applications. This high gas pressure switch features an adjustable setpoint range of 5" to 28" W.C., providing precise control for interlock circuits. Built with a DPDT (Double-Pole Double-Throw) configuration, it allows for the simultaneous management of two independent electrical circuits, making it ideal for standard safety shut-off and remote alarm signaling. The automatic reset (recycle type) functionality ensures the system re-engages once gas pressure returns to the safe operating range below the OPEN-HI trip point.

Housed in a rugged die-cast aluminum enclosure, the 803114001 is engineered to withstand demanding boiler room environments. It utilizes a 1/4" NPT gas inlet and a 1/8" NPT vent connection, ensuring compatibility with standard manifold piping. As a veteran-preferred Antunes 803114001 component, this unit is UL listed, FM approved, and CSA certified, meeting strict safety codes for combustion safeguard systems. Its horizontal mounting capability and clear setpoint scale allow for straightforward field calibration and high-reliability performance in varied pressure-monitoring loops.

• DPDT Switch Logic: Features DPDT 803114001 electrical contacts to control multiple safety interlocks or auxiliary signals from a single device.
• Wide Adjustable Range: Monitors 5-28" water column gas pressure, allowing for fine-tuned protection against over-pressure conditions.
• Industrial Durability: Constructed with a die-cast aluminum housing to protect internal mechanisms from mechanical stress and debris.
• Automatic Reset: The RHGP-D series design eliminates the need for manual intervention after momentary pressure spikes, maintaining system uptime.
• Standard Fitting: Equipped with a 1/4" NPT inlet and 1/8" NPT vent for universal gas pressure switch installation.

How do I adjust the setpoint on the Antunes 803114001?
Remove the cover and turn the internal range scale knob; clockwise increases the pressure setting, while counter-clockwise decreases it. Always verify the setting with a calibrated manometer during commissioning.

What is the difference between the HGP-D and RHGP-D models?
The "R" in RHGP-D stands for Recycle, meaning this is an automatic reset gas switch. Standard HGP-D models typically require a manual reset after a high-pressure trip.

Can this switch be used for low gas pressure applications?
No, the 803114001 is specifically an OPEN-HI 5/28" WC high gas pressure switch that breaks the circuit on pressure rise. For low-pressure monitoring, an LGP or RLGP series switch should be used.
