Harmony NFC 3-phase monitoring relay 8 A 2CO multifunction 208…480 V AC

This 3-phase control relay belongs to the Schneider Electric Harmony Control relays range. This 3-phase control relay is integrated with NFC technology which brings in digital operation instead of analog operation. This is a 8A multifunction 3-phase control relay which monitors 3-phase or 3-phase with Neutral network and has an adjustable time delay of 0.1s to 60min. With Harmony NFC App, different alarms can be combined using AND, OR and NOT logic to form unique monitoring combinations for the two relay outputs which are individually configurable. NFC 3-phase control relay is a single reference supporting 7 functions namely Phase loss, Phase sequence, Asymmetry, Undervoltage, Overvoltage, Under-frequency, and Over-frequency. The 3-phase control relay is IP20 (terminals), IP40 (housing), and IP40(front panel) protected. Furthermore, the 4 digit password enhances security by preventing unauthorized change of settings. This RMNF22 dimensions are 22.5mm (width) x 90mm (height) x 99mm (depth) and weighs 0.125Kg. It conforms to international standard EN/IEC 60255-1 and certifications like UL, CSA, CE, CCC, EAC, and RCM. It is sold as a single unit. Monitoring and testing are now intuitive as exact fault conditions can be identified through front LEDs and analyze data with Harmony NFC App. This saves time and boosts efficiency.
