Eaton 3-Phase Voltage Monitoring Relay, 200 to 500V AC Voltage Sensed, DIN Rail Mount - EMR6 Series - 184789 EMR6-F500-G-1 Keep track of the operating voltage of your equipment using this voltage monitoring relay from Eaton. It's designed to trigger a safety response if it detects an abnormal voltage value, protecting your system from downtime. For versatility, you can also use it to monitor the power supply of 3-phase motors and detect if phase failure or phase sequence occurs. This unit has a broad voltage sensing range between 200 and 500V AC for use in both low-voltage and high-voltage systems. • Mechanical durability rating of 30,000,000 cycles for long-term performance
• Wide operating temperature range between -20°C and +60°C for safe use in harsh environments
• DIN rail mounting for quick installation
• LED indicators for simple status configuration
• Shock-resistant to prevent false tripping What's do 'phase failure' and 'phase sequence' mean? Phase failure is when complete loss of one or all phases in a 3-phase system occurs, causing machine shutdown. Phase sequence refers to the successive activation of each phase of the motor based on a defined parameter.
