Description
The United Electric H54-25 differential pressure switch is a reliable, field-adjustable control designed to monitor pressure differences across filters, coils, and fluid systems in HVAC and industrial applications. With an adjustable differential range of 10 to 100 PSI, this switch provides accurate and repeatable response for system protection, flow verification, and maintenance indication. The SPDT (single-pole, double-throw) contact configuration allows for flexible control of normally open and normally closed circuits. Built for durability and consistent performance, the H54-25 is well-suited for demanding environments where dependable differential pressure monitoring is required.
