United Electric H54-27 Pressure Switch
The United Electric H54-27 Pressure Switch is a rugged, NEMA 1 rated control solution engineered for reliable pressure monitoring in HVACR and industrial service. This model features an adjustable setpoint range of 30 to 300 PSI, providing precise field calibration via an internal reference dial. With its SPDT switch output rated for 15A at 125/250/480 VAC, the H54-27 facilitates seamless integration into safety alarm, compressor staging, or system shutdown circuits. The unit is constructed with a Buna-N diaphragm and an aluminum 1/4" NPT pressure connection, ensuring compatibility with various non-corrosive air and liquid media. Designed for high-repetition OEM environments, this United Electric 54 series switch maintains a tight deadband of 1.6 to 4 PSI and features a proof pressure limit of 600 PSI. Technicians can rely on the black-finished Lexan enclosure for basic indoor ingress protection while ensuring repeatable actuation in demanding commercial thermal and pressure applications.
- Versatile Range: Internal reference dial allows for quick field adjustments across the 30 to 300 PSI spectrum.
- Industrial Durability: NEMA 1 Lexan enclosure protects internal components from debris in controlled environments.
- Flexible Connectivity: Single Pole Double Throw (SPDT) contact configuration supports both normally open and normally closed wiring.
- High Overpressure Limit: Engineered to withstand overrange pressures up to 100 PSI above setpoint without recalibration.
Common Questions
What is the maximum electrical rating for this switch?
The H54-27 is rated for 15 Amps at 125, 250, or 480 VAC resistive loads, making it suitable for direct motor control or high-voltage signaling.
Is this switch suitable for outdoor use?
This model is housed in a NEMA 1 enclosure, which is designed primarily for indoor use. For outdoor or washdown applications, a NEMA 4X rated switch is typically required.
Can the deadband be adjusted?
The deadband on the H54-27 is a fixed mechanical differential ranging from 1.6 to 4 PSI and is not field-adjustable.
