Schneider Electric FSG2M43050 Pressure Switch 30-50 Psi

Product Description

The Schneider Electric FSG2M43050 is a pressure switch designed to control water pump operation by automatically starting and stopping the pump based on system pressure. It is factory-set to cut in at 30 psi and cut out at 50 psi, with a maximum operating pressure rating of 70 psi. This type of switch is a standard control component in residential and light commercial water supply systems, including well pump pressure tanks. Installation and service are typically performed by licensed plumbers or pump service technicians.

This pressure switch is suited for use in well water systems where automatic pump cycling is required. It mounts directly to the pressure tank tee fitting and senses system pressure through a threaded port connection. The 30-50 psi differential range is one of the most common setpoints for residential well pump applications, making this a frequent replacement part in the field. It is not intended for use with compressed air or gas service lines.

Key Features

• Factory-set cut-in pressure of 30 psi and cut-out pressure of 50 psi
• Maximum system pressure rating of 70 psi
• Designed for automatic pump start and stop control in water pressure systems
• Standard threaded port for direct mounting to pressure tank tee fittings

Compatibility

Designed as an OEM-style replacement pressure switch for residential well pump and water pressure tank systems requiring a 30-50 psi cut-in and cut-out setpoint.

Installation Notes

Installation should be performed by a licensed plumber or pump technician. Before servicing, shut off power to the pump at the circuit breaker and relieve system pressure before disconnecting the existing switch. Wiring must comply with applicable NEC requirements for the supply voltage and amperage of the pump circuit. Do not exceed the 70 psi maximum pressure rating of the switch.
