Square D 9012G Pressure Switch

This Square D 9012G pressure switch monitors system pressure and opens or closes a circuit when the set point is reached. It operates on a 20 to 774 PSI range with an adjustable differential of 19 to 58.8 PSI. A 1/4-18 NPT port connects directly to the process line. The NEMA 1 enclosure is rated for indoor use.

Indoor pressure control for water.

Installers who need a reliable switch for pump control, compressor cut-out or hydraulic safety circuits will find the 1NO/1NC contact block suitable for both AC and DC loads. The diaphragm actuation handles media temperatures from -40 to 250 degrees F. Buyers who require a NEMA 4 or 7 enclosure for wash-down or hazardous locations should look at a different series.

Adjustable 20-774 PSI range with 1/4 NPT port

The single specification that decides fit is the pressure range combined with the port thread. The switch covers 20 to 774 PSI and fits a 1/4-18 FNPT connection. If the application demands a higher upper limit, a different port size or a wider differential, this model will not suit.

Questions about this item

How much power does the 9012G pressure switch draw when running continuously?

The switch itself is a passive diaphragm device and draws no power; only the circuit it controls consumes current, rated at 3 A at 120 V or 240 V AC and 0.22 A at 125 V or 0.27 A at 250 V DC.

What piping or fittings must I already have to install this 1/4-18 FNPT port switch?

You need a 1/4-18 NPT male fitting or adapter on your pressure line to thread into the single female port on the switch body.

Will the 9012G work with my existing 120 V AC control circuit that uses a standard relay coil?

Yes, the contacts are rated 3 A at 120 V AC, which is suitable for typical relay coils and pilot devices in that voltage class.
