H100 Model 3XX Pressure Switch

Brand: United Electric Controls Ltd
Does not ship to United States

The 100 Series is a cost-effective pressure and temperature switch for process plants and OEM equipment.

The rugged, one piece enclosure features a slanted cover for wiring accessibility. A wide variety of microswitch and process-connection options make this versatile series ideal for applications requiring a rugged weather-proof mechanical switch.

Typical applications that utilize the 100 Series are heat tracing, freeze protection, processing equipment (pumps, compressors), inputs for annunciator panels, and fire suppression systems.
