Phoenix Contact EMDFL3V400 3-Phase Voltage Monitoring Relay
The PHOENIX CONTACT EMD-FL-3V-400 is a versatile monitoring relay crucial for maintaining safety and system availability across various industries, including mechanical engineering, chemical processing, and automation technology. It continuously monitors 3-phase voltages, providing protection against undervoltage, phase sequence errors, phase failure, and asymmetry. The relay features adjustable settings via a front potentiometer, a wide-range power supply, and a floating contact for system shutdown or control. Its robust design and compliance with EMC and LV directives make it suitable for demanding industrial environments. The relay's ability to tolerate measured values outside the set monitoring range through adjustable response delays further enhances its reliability and adaptability.
