Schneider Electric (Square D) 9013FSG2J20P Switch

For contractors servicing residential or light commercial water systems, the Schneider Electric (Square D) 9013FSG2J20P Switch remains the industry standard for electromechanical pressure regulation. This Square D Pumptrol pressure switch is factory-set for a 20 PSI cut-in and 40 PSI cut-out, featuring a DPST (Double Pole Single Throw) contact arrangement. Built for durability, the 9013FSG2J20P model includes a pulsation plug to minimize surges and protect the internal diaphragm in high-vibration environments. It is compatible with jet, submersible, and reciprocating pumps, handling up to 1.5 HP at 120V or 2 HP at 240V. The adjustable differential 20/40 switch allows for field tuning between 15 to 30 PSI, ensuring precise control over system cycling. Professionals value the NEMA 1 enclosure and the rugged 1/4" FNPS internal thread connection for reliable, long-term performance in water-pumping applications.

• Broad Compatibility: Rated for single-phase and three-phase motors, supporting up to 2 HP at 230V systems.
• Precision Engineering: Features a pulsation plug to prevent contact chatter and extend the life of the switch and motor.
• Field Serviceable: The adjustable differential pressure switch mechanism allows for fine-tuning the operating range between 5 and 65 PSI.
• Simplified Wiring: Large screw-clamp terminals accommodate 10 AWG wire, and the captive cover nut prevents hardware loss during installation.
• Contaminant Resistance: Designed with vertical contacts to prevent debris and carbon buildup from interfering with electrical continuity.

What is the purpose of the pulsation plug in the 9013FSG2J20P?
The pulsation plug is integrated into the 1/4" input port to dampen pressure spikes or water hammer. This prevents the switch from rapid cycling and protects the internal diaphragm from premature wear.

Can I adjust the factory 20/40 PSI settings?
Yes, while it comes pre-set at 20 PSI on and 40 PSI off, the Square D 9013FSG2J20P is fully adjustable. Using the large nut on the internal spring, you can shift the range while maintaining the differential.

Is this switch suitable for submersible well pumps?
This DPST water pump switch is universal for all domestic water systems, including deep-well submersibles, provided the motor amperage does not exceed the 10A rating at operating voltage.
