VMR Voltage-Monitoring Relays

Trumeter VMR Voltage-Monitoring Relays support multi-voltage inputs, operating on three-phase, three-wire systems at 208V to 480V with true RMS measurement for accurate monitoring. VMR relays can monitor the relay's power supply and detect fault conditions across one or more phases. This monitoring capability provides comprehensive protection against under-voltage (UV), over-voltage (OV), phase asymmetry, incorrect phase sequence, phase loss, and three-phase interruptions. These voltage-monitoring relays also feature selectable ON or OFF time delays with adjustable settings, ensuring optimal performance and system protection. A single change-over relay (Form C) allows for reliable switching. LED indicators provide clear status updates for all faults and alert users to changes in dip switch settings during runtime, enhancing security.
