400 Series Pressure, Vacuum, Differential Pressure

and Temperature Switches

 

 

The 400 Series is a versatile family of vacuum, pressure, differential pressure and temperature switches for applications 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.

 

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. Its worldwide use is assured with approvals and certifications to agency standards.

 

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

Vibration                                      Set point repeats after 2.5 G, 5-500 Hz

 

Enclosure                                     Die cast aluminum, epoxy powder coated, gasketed, captive cover screws

 

Enclosure Classification            Designed to meet enclosure type 4X requirements

 

Switch output                              One, two or three SPDT switches, may be separated up to 100% of range

                                                         except models 521-524, 531-534: 50%; models 520, 525, 530, 535, 570-572:

                                                         30%; switches may be wired “normally open” or “normally closed”

 

Electrical rating                           15 A 125/250/480 VAC resistive. Electrical switches have limited DC

                                                         capabilities. Consult factory for additional information.
