C6097B3051 Honeywell 1.5–7# NPT Pressure Switch – Break on Rise
🔍 Product Overview
The Honeywell C6097B3051 is a high-performance pressure switch designed for gas or air systems. It operates in positive-pressure or differential-pressure environments to monitor system safety and ensure reliable operation. This model breaks the control circuit at setpoint on pressure rise, protecting equipment from unsafe conditions.
Compatible with industrial, commercial, and residential HVAC and combustion systems, it replaces multiple Honeywell models including C6097B1044, C6097B1051, and C437D2011.
🌟 Key Features
✅ Operating Pressure Range 1.5–7 psi – Wide flexibility for gas and air applications
✅ Break on Pressure Rise – Ensures system shuts off at high pressure setpoints
✅ Differential Subtractive Design – Reliable pressure sensing with precise cut-off
✅ 240 VAC Rated – Compatible with standard control circuits
✅ IP65 Protection – Dust-tight and water-resistant for harsh environments
✅ 1/4" NPT Connection – Easy installation into existing piping systems
✅ Temperature Range -40 to 140°F (-40 to 60°C) – Durable in extreme conditions
✅ Maximum Pressure 8.5 psi (600 mbar) – Safe operation beyond typical setpoints

❓ Frequently Asked Questions (FAQ)
Q1: What does “break on rise” mean?
➡️ The switch interrupts the control circuit when pressure exceeds the setpoint.
Q2: Can this be used with both gas and air?
➡️ Yes, it’s designed for both gas and air positive-pressure or differential-pressure systems.
Q3: What models does this replace?
➡️ C6097B1044, C6097B1051, C437D2011.
Q4: What is the maximum pressure this switch can handle?
➡️ 8.5 psi (600 mbar).
Q5: Is it suitable for outdoor or harsh environments?
➡️ Yes, with IP65 protection, it is dust-tight and water-resistant.
🛒 Shopping Tips
✅ Verify your system’s pressure range before ordering.
✅ Inspect NPT connections for wear or leaks.
✅ Replace if pressure readings are inconsistent or cut-offs fail.
✅ Ensure voltage rating matches your control circuit (240 VAC).
✅ Use gloves or thread sealant to prevent leaks during installation.
