United Electric H100-218 Vacuum Switch
The United Electric H100-218 Vacuum Switch is a heavy-duty, field-adjustable control engineered for precise vacuum pressure monitoring in demanding industrial and HVACR environments. This SPDT vacuum switch features a rugged, NEMA 4X epoxy-coated aluminum enclosure, making it a reliable choice for protecting pumps, compressors, and heat tracing systems against negative pressure excursions. With a 1/4" FNPT nickel-plated brass connection and phosphor bronze bellows, the H100-218 offers a measurement range from 30" Hg Vac to 0 PSI, ensuring critical system safety and process control. Technicians appreciate the internal tamper-resistant setpoint lock and the high/low reference scale, which simplify calibration during routine maintenance. Designed for low pressure vacuum sensing, this adjustable vacuum switch provides a standard 15A contact rating, allowing for seamless integration into industrial automation safety loops or alarm circuits. Its 1% repeatability and fixed deadband make it an essential HVAC vacuum control component for maintaining long-term system uptime and equipment protection.
Key Benefits for the Contractor- Rugged Durability: The NEMA 4X housing provides superior resistance to corrosion and moisture, ideal for wash-down or outdoor installations.
- Precise Control: Features a high-quality phosphor bronze bellows to ensure accurate vacuum sensing with 1% repeatability.
- Easy Installation: The 1/4" FNPT connection and accessible wiring compartment through the slanted cover reduce labor time during field setup.
- Versatile Signaling: The SPDT switch output provides flexible wiring options for normally open or normally closed logic in safety and control circuits.
Is the setpoint adjustable in the field?
Yes, the United Electric H100-218 features an internal adjustment screw with a reference scale for easy field calibration without specialized tools.
What is the maximum proof pressure for this model?
This unit is designed specifically for vacuum; while the operating range is 30" Hg Vac to 0 PSI, it has a proof pressure rating of 30 PSI to prevent damage from accidental over-pressurization.
Can this switch be used in wash-down environments?
The NEMA 4X enclosure is specifically designed for harsh environments, offering watertight and dust-tight protection that meets industrial epoxy-coating standards.
