Description
Honeywell C6097B3028 Pressure Switch – Manual Reset, 1/4" NPT, 1 to 20 in. W.C., Subtractive The Honeywell C6097B3028 is a robust manual-reset pressure switch designed for safety in positive, negative (air/flue gas), or differential pressure systems. It features a diaphragm-actuated mechanism to detect pressure rises, breaking the control circuit to prevent unsafe conditions. Built for durability and safety, it includes a transparent cover, external manual reset button, and is rated IP65 for protection in demanding environments. Key Features Manual reset pressure switch with external reset button for safety lockout Diaphragm-actuated safety-limit switch for reliable pressure sensing Breaks normally closed (NC) to common (COM) circuit on pressure rise (subtractive) Suitable for gas and air pressure monitoring in HVAC and combustion systems Transparent removable cover protects scaleplate and adjustment knob Additional inlet filter pad for gas/air protection Safety cover over screw terminals Optional switch position indicator lamp available IP65 rated enclosure for dust and water resistance Certified by FM and UL for safety compliance Technical Specifications Parameter Details Product Type Manual Reset Pressure Switch Pressure Range 1 to 20 in.
