United Electric Controls H400-361 Pressure Switch 0 to 300 PSI 0-2068.4 kPa

Description:

The United Electric Controls H400-361 Pressure Switch is used in industrial process control systems to monitor pressure and provide automatic electrical switching when preset pressure levels are reached. Commonly installed in pumps, compressors, hydraulic systems, water treatment equipment, process machinery, and industrial automation applications requiring reliable pressure monitoring and equipment protection. Maintenance teams and system integrators use this part for repair, retrofit, expansion, or replacement of existing pressure sensing and control systems.

Applications:

The United Electric Controls H400-361 Pressure Switch is commonly used in pump protection systems, compressor control circuits, hydraulic power units, process pressure monitoring, safety shutdown systems, and industrial alarm applications. The switch utilizes a pressure-actuated sensing mechanism to detect pressure changes and actuate electrical contacts for alarms, interlocks, shutdown functions, and automatic process control, helping maintain safe and efficient operation of critical industrial equipment operating in medium-pressure applications.
