Grundfos Float Switch GRFSFSW

The Grundfos Float Switch GRFSFSW is a reliable accessory designed for precise liquid level control in pump systems. Engineered to work seamlessly with Grundfos pumps, it ensures automatic activation or deactivation based on fluid levels, protecting equipment and preventing overflow or dry run. Its robust build guarantees durability in demanding environments, making it ideal for both residential and industrial applications where accurate monitoring is critical.

This is for the CU-200 Grundfos Pump Controller or other pump controller that uses solid state switching (that is, NOT in line with main AC power). Sensor float switches are used for low current devices such as magnetic contactors or pump control panels. The GF-100 is a low cost, three wire sensor float switch and is normally open in the down position. It is a mechanical activated switch and is NSF approved for potable water. If used with a Sun Pumps PC-Series controller it can be either a Pump-Up or a Pump-Down switch because the controller has a logic reversing circuit allowing easy logic change for any desired application. If used with the Grundfos CU-200 controller, it becomes a Pump-Up switch. It will turn the pump off when the tank is full. Maximum power rating: 5 Amps 125/250 VAC 50/60 Hz. This is a 3-wire switch, green/yellow stripe is ground. (Shown with optional pivot weight, not included.)
