Heavy Duty Pressure Switch, 30-50 PSI, 1/4" Female NPT Connection Rated 5HP

The Merrill MPSXHD3050 extra heavy-duty pressure switch outperforms the competition with its extra-large, heavy-duty case for easy wiring. It features heavy brass wire connections securely holding No.4 wire with set screws to prevent slipping and is ideal for higher horsepower pumps. The Merrill MPSXHD6080 pressure switch signals the pump to start when the water system cuts in at 30 psi (factory set) and cuts out at 50 psi (factory set). The MPSXHD3050 is factory set and is a very reliable pressure switch for consistent water pressure management.

• Factory preset to automatically turn the pump on at 30 psi and off at 50 psi
• Brass contacts for better electrical conductivity
• Heavy brass wire connections (hold no.4 wire) with set screws that will not slip off
• ¼” swivel union so switch case does not need to be pivoted to install
• Heavy fiberboard bracket for movement of contacts is much stronger and heat resistant
