Description
The United Electric J40-230 pressure switch is a field-adjustable control designed for general-purpose pressure monitoring in HVAC, compressor, and light industrial systems. With an adjustable setpoint range of 0 to 100 PSI, this switch provides reliable performance for system cycling, alarm activation, and equipment protection. The unit features a 1/4" NPT pressure connection for standard piping compatibility and straightforward installation. The SPDT (single-pole, double-throw) contact configuration allows for flexible wiring of normally open and normally closed circuits. Housed in a NEMA 1 enclosure, the J40-230 is intended for indoor use where basic protection from dust and incidental contact is sufficient.
