Pressure switch for air and water systems

This Square D 9013GH pressure switch controls air compressors and water pumps in residential or light-industrial settings. It provides a factory-set on/off range of 100 to 125 psi with a differential of 20 to 40 psi. The unit carries a NEMA 1 rating and a single 1/4 in FNPS port for straightforward installation.

Suited for standard compressor and pump circuits

The switch handles up to 10 A with DPST contacts and is rated for 2 hp at 120 V single-phase, 3 hp at 240 V single-phase, and 5 hp at 240 V or 480 V three-phase. It is not intended for applications requiring an integrated unloader valve or for environments needing a higher NEMA enclosure rating.

Fits directly into existing pressure lines

The single port threads into the system without extra fittings, while the manual Auto/Off/On lever gives immediate local control. Standard-action operation replaces many legacy switches in the 40 to 200 psi adjustable range, freeing panel space that a separate unloader assembly would otherwise occupy.

Questions about this item

What pressure system do I need already installed for this 100-125 psi switch to operate?

This switch requires an existing air compressor or water pump system that operates within the 40-200 psi range and has a 1/4 inch FNPS port for connection.

Will this DPST switch replace the controller on my older single-phase 120V motor?

Yes, it supports up to 2 hp at 120V single-phase, so it can control compatible older motors within that power rating.

How do I verify the 20-40 psi differential is working after wiring the switch?

Observe the pressure gauge: the compressor should start at 100 psi and stop at 125 psi, confirming the factory on/off settings are active.
