The NEX Series® duplex control panel is designed to alternately control two 120, 208, or 240 VAC single
phase pumps in water and wastewater applications. The alternating action equalizes pump wear. In addition,
this system provides override control should either pump fail. If an alarm condition occurs, an alarm switch
activates the audible/visual alarm system. The compact design (25.4 x 20.32 x 10.16 cm) is ideal for residential
applications. Universal pump voltage and control/alarm power allow the NEX Series® panel to handle three voltages (120/208/240V single phase). The innovative design of internal components and integral mounting tabs make installation quick and simple.

Typical application including lift pump chambers, sump pump basins, holding tanks, sewage and other water applications.
