The 400 Series is a versatile family of vacuum, pressure, differential pressureandtemperatureswitchesforapplicationsthatrequiresingle 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. UL listed and cUL certified. FM approved. CE compliant to low voltage directive and pressure equipment directive. 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....
