Application and brief description
The SW32V voltage relay is a high-quality voltage monitor with a large measurement range for monitoring
direct, alternating and three-phase networks for overvoltage and/or undervoltage. In three-phase current
networks, phase symmetry and phase sequence can be monitored in addition.
The limits are set in volts. That allows using the unit with various rated voltages.
The digital display is used to display the measurements and to precisely set limits, response times and
functions.
