Why Choose the Lovato PMV95NA575NFC Multifunction Monitoring Relay?
The Lovato PMV95NA575NFC is an advanced multifunction voltage and frequency monitoring relay designed to protect three-phase electrical systems against abnormal supply conditions. Suitable for systems with or without a neutral connection, it operates across a wide 380–575 V AC voltage range at 50/60 Hz.
As part of the Lovato PMV95N series, this self-powered monitoring relay provides comprehensive supervision of minimum and maximum voltage, minimum and maximum frequency, phase loss, neutral loss, incorrect phase sequence and voltage asymmetry. These monitoring functions help protect motors, drives, pumps, compressors and other sensitive industrial equipment from potentially damaging electrical faults.
The PMV95NA575NFC includes integrated NFC technology, allowing its operating parameters to be configured quickly using a compatible smartphone and the Lovato NFC application. This enables convenient programming without complex front-panel controls and allows settings to be prepared before the relay is powered or installed.

Advanced Three-Phase Supply Protection
Abnormal voltage, unstable frequency, missing phases and incorrect phase rotation can cause overheating, reduced performance or permanent damage to industrial electrical equipment. The Lovato PMV95NA575NFC continuously monitors the connected supply and changes the state of its relay output when programmed limits or fault conditions are detected.
Its NFC interface allows installers and maintenance engineers to configure protection thresholds and timing parameters using a mobile device. Settings can be applied accurately and consistently across multiple relays, helping reduce commissioning time in control panels and industrial machinery.
