Protect your well pump and maintain consistent water pressure with the Water Source PSL3050 Low Cut-Off Pressure Switch. Engineered for reliability and safety, this switch is designed to automatically start and stop your pump based on preset pressure thresholds, while also providing critical protection against low-pressure conditions that could damage your system.

The PSL3050 is factory-set to activate the pump at 30 PSI and shut it off at 50 PSI. It features a built-in low-pressure cut-off arm that automatically disables the pump when a sudden drop in pressure is detected—such as from a leak or a faulty pressure tank—helping prevent pump burnout and costly repairs.

Key Features

Low Pressure Protection: Automatically shuts off the pump when pressure drops dramatically, preventing damage.
Factory-Set Operation: Starts pump at 30 PSI and stops at 50 PSI for consistent water system performance.
Manual Reset Lever: Allows safe restart after low-pressure shutdown; must be held until pressure reaches 30 PSI.
Dual Voltage Compatibility: Can be wired for 115V or 230V systems.
Adjustable Pressure Settings: Two-spring design allows for cut-in and cut-out pressure adjustments.
Universal Wiring: Motor wires connect to center terminals; breaker box wires to outer terminals—color does not matter.
Durable Construction: Built for long-term use with submersible or jet pumps.
Peace of Mind: Prevents pump burnout due to dry conditions or system failures.
