Material: Plastic and metal construction for durable, long lasting performance. Electrical compatibility: 240V AC operation; supports up to 75 kW pump power; includes 1 normally open (NO) and 1 normally closed (NC) contact for flexible control. Design and usability: Orange double float switch for clear sensing and easy installation and operation. Key benefits: Automates pump control to prevent dry running and overflow, reducing manual monitoring and enabling reliable integration with standard control circuits. Use scenarios: 1) Factory water storage tank level control to autostop the pump at level. 2) Home well or cistern pump management to maintain desired water level and protect equipment. 3) Water towers or large reservoirs requiring automatic level regulation. Applications: Suitable for factories, household water pumps, water storage tanks, water towers, and other tank and pump setups needing level control.
