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. As an electromechanical switch, it can safely operate independently of the control system and switch reliably when called upon, free from potential communication errors or cyber concerns.

Typical applications that utilize the 400 Series include regulating industrial gas production, and controlling assets like pumps, turbines, and compressors.

    • 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
    • Replaces a switch and a gauge in differential pressure applications when using optional visual indication
