Lovato PMV95NA575NFC self-powered multifunction voltage and frequency monitoring relay for three-phase systems with or without neutral, featuring NFC programming and a 380 to 575 V AC operating range.
£189.69
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.
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.

It monitors minimum and maximum voltage, minimum and maximum frequency, phase loss, neutral loss, incorrect phase sequence and voltage asymmetry in three-phase electrical systems.
The relay is designed for three-phase systems operating between 380 and 575 V AC at 50/60 Hz.
Yes. The PMV95NA575NFC can monitor three-phase electrical systems either with or without a neutral conductor.
The relay is configured using integrated NFC technology and the compatible Lovato mobile application, allowing monitoring thresholds and timing parameters to be adjusted from a smartphone.
No. The relay is self-powered from the monitored three-phase supply, helping simplify installation and control-panel wiring.
Lovato multifunction monitoring relays are used by panel builders, automation engineers and equipment manufacturers to provide dependable protection against voltage, frequency and phase-related faults in industrial electrical systems.
