Description
The United Electric H100K-544 SPDT Differential Pressure Switch is designed to monitor and control differential pressure within HVAC systems and industrial process equipment. With an adjustable operating range of 220 PSID and a NEMA 4X enclosure, it responds to pressure changes by actuating a single-pole double-throw electrical contact. Commonly installed in air handling units, filtration systems, pumps, and refrigeration equipment, this pressure switch works as a essential control and maintaining component, supporting reliable system operation, pressure monitoring, and controlled equipment operation.
