Pressure Switch for Air and Water Systems

The Telemecanique Sensors 9013GHG2J58 is a DPST pressure switch designed for air compressors and water pumps. It features a single 1/4 inch FNPT port and a factory on/off setting of 125/150 psi. The switch operates with a standard action and carries a NEMA 1 rating for general indoor use. It suits installers needing a direct replacement for industrial pressure control.

Sustained Operation and Electrical Ratings

Under continuous cycling the switch manages a differential range of 20 to 40 psi within an overall range of 40 to 200 psi. It is rated for 2 hp at 120 V single phase and 3 hp at 240 V single phase. Three phase ratings reach 5 hp at both 240 V and 480 V. No unloader valve is included so the compressor head sees full back pressure on restart.

Deciding Specification

The factory preset cut-in and cut-out pressures of 125 and 150 psi determine whether this switch matches the system design. Buyers needing a different pressure band or an adjustable unloader must select another model. The fixed 20 to 40 psi differential also limits fine tuning for narrow pressure windows.

Questions about this item

How much does the pressure differential of 20 to 40 psi affect compressor cycling during all-day operation?

The switch uses a 20 to 40 psi differential between the 125 psi cut-in and 150 psi cut-out settings, so the compressor runs less often than with a narrower spread.

What pipe fitting must I already have to connect the 1/4 in FNPS port?

You need a male 1/4 in NPS thread on your air or water line to mate with the female port on the switch.

Will the DPST contacts handle the 3 hp rating of my existing 240 V three-phase motor?

Yes, the contacts are rated for 3 hp at 240 V three-phase, matching that motor size.
