Description
The United Electric J54-25 differential pressure switch is a field-adjustable control designed to monitor pressure differences in HVAC, filtration, and industrial process systems. With an adjustable differential range of 10 to 100 PSI, this switch provides reliable performance for applications such as filter condition monitoring, flow verification, and system protection. The SPDT (single-pole, double-throw) contact configuration allows for flexible control of normally open and normally closed circuits. Housed in a NEMA 1 enclosure, the J54-25 is intended for indoor use where basic protection from dust and incidental contact is sufficient. Its durable construction ensures consistent and repeatable operation in standard environments.
