Multifunction measuring relay MK 9300N The universal measuring relays MK 9300N / MH 9300 of the VARIMETER PRO series monitor up to 9 parameters simultaneously. These are under-, over-voltage, voltage range, voltage asymmetry, under-, overcurrent, cos phi, effective-, apparent- and reactive power, frequency and phase sequence, The measurement in 3-phase or single-phase systemes is very simple and without extensiv wiring. Because of the menue structure the multifunctional measuring relays can be used easyly and intuitively. The early detection of up-coming break downs and preventive maintenance avoid expensive damages. As user you profit from the reliability and availability of your plant. Advantages .
