United Electric's 400 series is a simple, economical temperature control for processes that require multiple switching capabilities. Dual or triple switch controls provide multi-output in applications such as alarm and shutdown, pre-alarm and alarm, high/low limit, or level staging functions. A wide variety of microswitch and process connection options, along with a weather-tight enclosure, make the 400 Series an ideal choice for most ordinary location applications.

Widely used throughout the process industries, the 400 Series provides threshold protection and control for many critical functions. Typical installations include industrial gas production, energy generation, pumps, turbines and compressors, pulp and paper, and water and wastewater treatment.
