SK-9 230V 1-phase pressure switch – Automatic control for water pump – Operating pressure 6 bar – Adjustment range 1.4 to 4.1 bar

General Description: The SK-9 pressure switch is an essential device for domestic water installations operating at 230V. It is designed to automatically control water pumps, including those used in wells and gardening systems. This mechanical pressure switch allows for continuous adjustment of the start and stop pressure, ensuring optimal operation of your water system. Technical Specifications: Input Voltage: 220-240V; Maximum Current: 10A; Operating Pressure: 6 bar; Pressure Adjustment Range: 1.4 to 4.1 bar; Start Pressure: 1.4 - 2.8 bar; Package Dimensions: Height 110 mm, Length 105 mm, Width 65 mm; Weight: 0.376 kg; Material: Metal/Plastic; Color: Black; Protection Class: IP44 (splash-proof); Connections: 13 mm (1/4 inch); Temperature Range: 0 - 55°C. Installation: To install the pressure switch, follow these steps: Loosen the differential nut; Set the start pressure; Tighten the differential screw to the stop pressure. If your pump has a higher power rating... At 1.1 kW, it is recommended to use a suitable power connector or relay. For a 380/400V three-phase pump, a 380V power connector is required. Operation: The SK-9 pressure switch automatically activates the pump when the water pressure drops below a certain limit. Once the pressure is restored, the pump stops, ensuring effective water control in your system. Other information: Part number: 50622 WEEE registration number: DE45283704
