Antunes Controls 804112102 Pressure Switch

When you are managing a high-stakes commercial burner or boiler system, the Antunes Controls 804112102 (Model RHLGP-A) is the industry standard for integrated gas pressure monitoring. This dual-function high and low gas pressure switch is engineered to break the electrical control circuit if gas pressure exceeds the 5-28" W.C. high setpoint or falls below the 1-6" W.C. low setpoint. The automatic reset mechanism ensures the system resumes operation immediately once pressure levels return to the safe, programmed range, minimizing downtime for your clients. Built with a rugged die-cast aluminum housing, this unit stands up to demanding mechanical room environments and can be mounted horizontally without requiring precise leveling. For seamless field integration, it features a 3/8" NPT high pressure connection, a 1/8" NPT low pressure connection, and a 1/8" NPT vent. As a 2-SPDT gas pressure switch, it provides the versatile electrical switching needed for sophisticated safety interlock strings in modern HVACR applications.

• Dual-Point Monitoring: Consolidates high and low pressure sensing into a single, compact RHLGP-A housing for simplified piping and wiring.
• Broad Operating Range: Adjustable high-side (5-28" W.C.) and low-side (1-6" W.C.) scales allow for precise gas pressure safety limit calibration.
• Heavy-Duty Reliability: Features an FM approved pressure switch rating and UL/CSA certifications for compliance with strict industrial safety codes.
• Technical Versatility: The SPDT electrical rating (10A @ 125 VAC) handles inductive motor loads or pilot duty signals with ease.

What is the maximum surge pressure for the Antunes 804112102?
This model is rated for a maximum surge pressure of 10 PSI, protecting the internal diaphragm during initial system firing or regulator surges.

Can the RHLGP-A be used in extreme temperature environments?
Yes, the Antunes Controls pressure switch is designed to operate in ambient temperatures ranging from -40°F to 140°F (-40°C to 60°C).

Is this an automatic or manual reset switch?
The 804112102 is an automatic reset pressure switch, meaning it will clear the fault once pressure stabilizes without requiring a physical reset by a technician.
