The Phoenix Contact Monitoring relay for monitoring 3-phase voltages of 400 V AC ±30%. Safety and system availability requirements are constantly on the increase – across all industries. Processes are becoming more and more complex, not only in machine building and the chemical industry but also in building technology. The demands placed on energy technology are also constantly on the rise. It is only by continuously monitoring key network and system parameters that error-free and therefore cost-effective operation can be achieved.
