Remco Industries 3300-PSW Pressure Switch Assembly 45-74 Psi

Product Description

The REMCO INDUSTRIES 3300-PSW is a pressure switch assembly from the 3300 Series, designed to monitor and respond to system pressure within a 45 to 74 PSI operating range. Pressure switches in this class open or close an electrical circuit when system pressure crosses a set threshold, making them a core component in fluid handling, pump, and HVAC control applications. The 3300-PSW ships as a complete assembly, reducing field time during installation or replacement. Licensed plumbers, HVAC technicians, and pump service professionals are the typical installers for this type of switch.

The 3300-PSW is suited for residential and light commercial systems where pressure monitoring and automatic shutoff or activation is required. Typical applications include water pressure control in pump systems, pressure sensing in hydronic heating circuits, and similar fluid-based control scenarios. The 45 to 74 PSI range makes it appropriate for standard domestic and commercial water service pressures as well as low-pressure HVAC hydronic loops.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician familiar with pressure control devices. Always depressurize and de-energize the system before removing or installing any pressure switch. Verify that system operating pressure falls within the 45 to 74 PSI rated range before commissioning. Applicable work should conform to local plumbing codes and relevant sections of the IPC or IFGC as required by the installation type.
