UNITED ELECTRIC J400-448 PRESSURE SWITCH 480VAC 15A 225 PSI

Description:

The United Electric Controls J400-448 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 compressors, pumps, hydraulic systems, process equipment, water treatment systems, 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 J400-448 Pressure Switch is commonly used in compressor control circuits, pump protection systems, 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 environments.
