Square D FSG2J24CP Pressure Switch 40/60 Psi

Product Description

The SQUARE D FSG2J24CP is a standard pressure switch rated for 40/60 PSI cut-in and cut-out operation on electrically driven water pump systems. It features a 1/4-18 NPSF internal thread connection for direct mounting to pump pressure lines or tanks. This switch monitors system pressure and signals the pump motor to start and stop at the set thresholds, maintaining consistent water pressure throughout the system. It is a common component in residential and light commercial well pump installations and is typically installed by licensed plumbers or pump service technicians.

The FSG2J24CP is designed for use with electrically driven water pumps, including submersible and jet pump configurations. The 40 PSI cut-in and 60 PSI cut-out settings are among the most widely used pressure differentials for residential well and pressure-booster applications. Its internal thread inlet accepts standard fittings found on pressure tank tees and pump outlet assemblies, making it a practical replacement or new-installation component in water supply systems.

Key Features

• 40 PSI cut-in and 60 PSI cut-out pressure settings for standard pump cycling

Compatibility

Designed as an OEM-style replacement pressure switch for electrically driven residential and light commercial water pump systems requiring 40/60 PSI cut-in and cut-out operation.

Installation Notes

Installation should be performed by a licensed plumber or pump technician. Shut off power to the pump motor and relieve system pressure before removing or installing any pressure switch. Connections must comply with applicable local plumbing codes and NEC requirements for pump control wiring. Do not overtighten the threaded inlet connection, as this can damage the switch body or fitting.
