SQUARE D 9013FY Pressure Switch 50-70PSI 1Port 10A

Pressure Switch 9013FY 50-70PSI

The Square D 9013FY is a pressure switch designed to control water pump systems automatically. It monitors system pressure and activates the pump motor when pressure drops to the cut-in point, stopping it again at the cut-out point. This unit suits residential, agricultural, or light commercial installations where reliable pressure regulation is required. The DPST contact form handles both legs of the supply circuit for safer switching.

Upgrade from manual or fixed-range switches

This switch replaces manual pump controls or older switches with non-adjustable ranges that cannot match the 50 to 70 psi factory setting. The jump is worth it when the system demands a 20 to 30 psi differential and a broader 5 to 80 psi adjustable range for fine-tuning. It supports motors up to 2 hp at 120 V single-phase, 3 hp at 240 V single-phase, and 5 hp at 240 V three-phase, covering larger pumps that smaller switches cannot carry.

Sustained load behaviour

Under continuous cycling the DPST contacts maintain stable operation across the full 5 to 80 psi range without unloader assistance. The NEMA 1 enclosure protects the mechanism in indoor or sheltered locations during extended duty cycles. Rated for 10 A, the switch handles the inrush and running current of compatible motors repeatedly, while the standard action ensures consistent cut-in and cut-out performance over time.
