Two 5A microswitches to cut two live phases of 220VAC system. 1.1 GPM ON, 0.5 GPM OFF To use with pumps and heaters. The flow switch has two 5A microswitches actuating together that provides 2 dry contacts. Contacts are closed when there is a water flow and open when there is no water flow. 2 dry contacts are for turning on and off two live wires of 220V AC three wire system in the USA. Micro Switch Rating: 2 x 5A Maximum 230V Turn On at and above 1.1 GPM flow Turn off at and below 0.5 GPM flow 1" PVC Inlet and outlet socket connections, Glue type, insert 1" pipe in to the flow switch and glue it. Wetted Surfaces - PVC, Polypropylene, Buna N, No metal parts in wetted area. Line Pressure: 90 PSI Temperature: Up to 110 deg F Underwriters Laboratories recognized. 2 x 5A dry contact. 1/2" Electrical Conduit Connection Note: 1. Adding flow switch in the line will add pressure drop and restrict the water flow. You can expect 10-15 GPM maximum water flow through our 1" flow switch depending on your water pressure. 2. Installation and troubleshooting instructions are available on our website.
