United Electric Controls 400 Series Pressure and Temperature Switches

FM-approved, NEMA 4X, multiple SPDT/DPDT switch output

The 400 Series is simple to install and operate, providing end-users multi-output alarm, safety and emergency shutdown functionality. It carries global agency certification.

  • Quick and easy installation with ample access to wiring compartment and simple set point adjustment using reference dial or calibrated gauge
  • Application versatility achieved through a variety of ranges, microswitches, sensors and process connections
