Item No: L404F1367

Overview Provide operating control with automatic limit protection for pressure systems up to 300 psi (2068 kPa). Features Use with steam, air, noncombustible gases, or fluids non-corrosive to pressure sensing element. Models have snap-acting switching to open or close a circuit on pressure rise. Have adjustable differentials. Adjustments are made by screws on top of case. Mount using 1/4 inch -18 NPT internal pipe threads or surface mount through base of case. Ground screw terminal.
