Cleveland Controls NS2-0404-00 Pressure Switch
The Cleveland Controls NS2-0404-00 Pressure Switch is a high-performance air flow pressure sensing switch designed for critical monitoring in commercial HVACR and industrial vacuum systems. Engineered with a durable glass-filled polycarbonate housing and a silicone diaphragm, this differential air pressure switch offers a fixed set point of 1.00" w.c. with a narrow switching differential for superior accuracy. Featuring a compression fitting sample line connection, the NS2-0400-00 facilitates secure, leak-free integration into rigid or flexible tubing runs. The internal SPDT snap-acting switch utilizes fine silver contacts rated for 1/10 HP at 120-277 Vac, ensuring reliable signal transmission for proving fans, blowers, or filter status. This OEM replacement pressure switch is factory-calibrated to maintain a low set point tolerance across a broad operating temperature range of -40°F to 190°F. For optimal performance, technicians should mount the unit with the diaphragm in a vertical plane to ensure consistent actuation and prevent moisture accumulation in the sample lines.
Key Benefits for Contractors- Stable Calibration: Factory-fixed 1.00" w.c. set point eliminates field adjustment errors and ensures precise HVAC pressure monitoring.
- Rugged Construction: The contaminant-free polycarbonate body resists degradation from combustion byproducts and harsh mechanical environments.
- Versatile Sensing: Capable of sensing positive, negative, or differential pressure, making it compatible with a wide array of furnace pressure switch and boiler applications.
- Standardized Connections: Equipped with 1/4" male quick-connect terminals and a compression fitting for rapid, technician-friendly installation.
- Industrial Reliability: Tested for 100,000 cycles minimum, providing long-term service in high-demand domestic and commercial air systems.
What is the maximum pressure rating for the NS2-0404-00?
This unit features a maximum pressure rating of 14" w.c., making it suitable for standard low-pressure air handling and draft inducement tasks.
Can this switch be used in residential furnace applications?
Yes, provided the OEM specifications call for a 1.00" w.c. fixed set point. It is a common replacement air switch for various high-efficiency heating systems.
Does the mounting orientation affect the set point?
Yes. To meet technical specifications and maintain the 1.00" w.c. calibration, the switch must be mounted with the diaphragm in a vertical position.
