Pressure switch for water pumps

The Square D 9013FR pressure switch controls water-pump operation with a factory-set 40/20 psi on/off range. It fits single-port systems using a 1/4 in FNPS connection and carries a 10 A SPST contact rated for 1 hp at 120 V or 240 V single-phase and 240 V three-phase.

Adjustable differential and wide temperature range

The differential can be set between 6 and 20 psi within a 4 to 45 psi operating window. A reverse-action mechanism and NEMA 1 enclosure allow installation in environments from -22 to 257 degrees F without an unloader valve.

10 A SPST contact rating decides compatibility

The single-pole single-throw contact rated at 10 A determines whether the switch can directly drive the pump motor or requires a contactor. Verify the motor’s full-load amperage against this rating before wiring.

Questions about this item

Will the 1/4 in FNPS port connection need periodic resealing?

The 1/4 in FNPS port uses standard pipe threads; apply fresh thread sealant whenever the switch is removed for inspection or replacement.

At the 40 psi cut-out, does the 10 A contact rating become the limiting factor?

The SPST contacts are rated 10 A at 120 V or 240 V single-phase, so the 10 A limit is reached before the 40 psi setting under normal motor loads.

How warm does the NEMA 1 enclosure get during continuous daily cycling?

The switch is rated for ambient temperatures up to 257 °F, so the enclosure remains within safe limits during all-day operation.
