United Electric (UE) 400 Series Multiswitch NEMA 4X Differential Pressure Switches

United Electric's 400 Series is designed for processes that require single or multiple switching capabilities. Dual and triple switch versions provide multi-output for alarm and shutdown, pre-alarm and alarm, high/low limit or level staging functions. The triple-switch J403 series can be used for liquid level control by setting outputs to correspond to "pumping out" elevations in a sump.

A wide variety of microswitch and process connection options, along with a weather-tight enclosure, make UE's 400 Series an ideal choice for most general service location applications. Widely used throughout the process industries, the 400 Series provides threshold protection and control for many critical functions.
