United Electric H100-704 Pressure Switch
The United Electric H100-704 pressure switch is a high-performance, electromechanical control designed for reliable monitoring in demanding HVACR and industrial process environments. This NEMA 4X pressure switch features a rugged, epoxy-coated die-cast aluminum enclosure, making it ideal for deployments requiring superior weatherproofing and corrosion resistance. Built with a Buna-N diaphragm and o-ring, the unit is optimized for air and non-corrosive media applications, providing a versatile 15 to 500 PSI adjustable setpoint range. The SPDT pressure switch output is rated at 15A @ 125/250/480 VAC, allowing for direct control of pumps, compressors, and annunciator panels without additional relays in many configurations.
Engineered for precision, the H100-704 offers a ±1% repeatability and a fixed deadband of 2 to 8 PSI, ensuring consistent performance. The internal adjustment mechanism includes a high/low reference scale for simplified field calibration, while the tamper-resistant setpoint lock prevents unauthorized changes once commissioned. For streamlined installation, the unit provides a 1/4 inch FNPT pressure connection and dual 7/8 inch knockouts for flexible wiring. Its ability to operate independently of digital control systems makes it a critical secondary safety layer for industrial pressure monitoring and fail-safe operations.
Key Benefits
- NEMA 4X Protection: Epoxy-coated aluminum housing provides a watertight and dust-tight seal for outdoor or washdown environments.
- Precise Control: Maintains ±1% setpoint repeatability across the entire 15-500 PSI range for critical system accuracy.
- High Load Capacity: Integrated 15A SPDT snap-action switch handles heavy electrical loads typically found in industrial motor and pump circuits.
- Industrial Durability: Features a proof pressure of 2,500 PSI and overrange protection up to 1,500 PSI to handle system surges without failure.
- Easy Maintenance: The clamshell design and slanted cover offer full access to terminal blocks for rapid field wiring and troubleshooting.
Common Questions
- How do you adjust the setpoint on the H100-704? The setpoint is adjusted internally by loosening the adjustment lock and turning the 5/8 inch hex screw to the desired level on the reference scale.
- Is this switch suitable for corrosive liquid media? The standard H100-704 uses a Buna-N diaphragm and nickel-plated brass connection; for highly corrosive chemicals, specialized wetted parts should be verified for compatibility.
- Can this be used for both rising and falling pressure? Yes, the SPDT (Single Pole Double Throw) configuration allows the switch to be wired to actuate on either rising or falling pressure conditions.
