UNITED ELECTRIC CONTROLS J400K-455 PRESSURE SWITCH J400K455

Description:

The United Electric Controls J400K-455 Differential Pressure Switch is used in industrial process control systems to monitor differential pressure and provide automatic electrical switching when preset pressure differentials are reached. Commonly installed in filtration systems, HVAC equipment, hydraulic circuits, lubrication systems, heat exchangers, and industrial process machinery requiring reliable differential pressure monitoring and equipment protection. Maintenance teams and system integrators use this part for repair, retrofit, expansion, or replacement of existing differential pressure sensing and control systems.

Applications:

The United Electric Controls J400K-455 Differential Pressure Switch is commonly used in filter monitoring systems, airflow proving applications, pump protection circuits, lubrication system monitoring, heat exchanger performance monitoring, and industrial alarm applications. The switch utilizes a differential pressure sensing mechanism to measure the pressure difference between two process points and actuate electrical contacts for alarms, interlocks, shutdown functions, and automatic process control, helping maintain safe and efficient operation of critical industrial equipment.
