United Electric H400K-456-M540 Pressure Switch
The United Electric H400K-456-M540 is a high-performance differential pressure switch engineered for precision monitoring in demanding HVACR and industrial process environments. This unit features a Viton diaphragm, providing superior chemical compatibility and thermal stability for systems handling aggressive media. With an adjustable range of 2 to 20 PSI, it allows technicians to fine-tune set points via an internal calibrated reference dial for reliable filter monitoring and flow verification. The SPDT switch configuration (Single Pole Double Throw) offers versatile wiring options for normally open or normally closed circuits, handling electrical loads up to 15A at 480 VAC. Housed in a rugged, epoxy-coated NEMA 4X enclosure, this switch is built to withstand washdown conditions, dust, and corrosive atmospheres. The 1/4 inch NPT process connections and 3/4 inch NPT electrical conduit opening ensure straightforward integration into existing pump and compressor control logic or boiler pressure safety strings.
Key Benefits for Contractors:- Viton Diaphragm: Ensures long-term durability when exposed to oils, chemicals, and elevated temperatures that compromise standard Buna-N sensors.
- Corrosion Resistance: The NEMA 4X aluminum housing protects internal components from oxidation in outdoor or high-humidity installations.
- Field Adjustability: Internal dial allows for accurate differential pressure scaling without the need for external calibration tools during routine maintenance.
- High Load Capacity: Rated for up to 480 VAC, making it suitable for direct integration into industrial motor control circuits.
- Vibration Resistance: Engineered to maintain set point stability even when mounted near heavy-duty reciprocating machinery.
What is the primary application for this differential switch?
It is typically utilized for detecting pressure drops across filters, monitoring liquid levels in pressurized tanks, or verifying flow status in chilled water and hydraulic systems.
Can this unit be mounted in any orientation?
While it can function in various positions, vertical mounting with the pressure connections facing downward is recommended to prevent moisture and sediment accumulation in the sensor housing.
Is the Viton diaphragm compatible with steam?
Viton is preferred for its temperature resistance; however, always verify the specific medium concentration and peak temperature against the United Electric chemical resistance charts to ensure optimal service life.
