This 3-phase control relay belongs to the Harmony control relay range from Schneider Electric. This 3-phase control relay is equipped with NFC technology which allows digital operation instead of analogue operation. This is an 8A multifunction 3-phase control relay that monitors 3-phase or 3-phase with neutral and has an adjustable time delay from 0.1s to 60min. Using the Harmony NFC App, different alarms can be combined with AND, OR and NOT logic to form unique monitoring combinations for the two relay outputs, which are individually configurable. The NFC 3-phase control relay is a single reference that supports 7 functions: phase loss, phase sequence, asymmetry, undervoltage, overvoltage, underfrequency and overfrequency. The 3-phase control is protected to IP20 (terminals), IP40 (housing) and IP40 (front panel). In addition, the 4-digit password increases security by preventing unauthorized changes to the settings. This RMNF22 has dimensions of 22.5 mm (width) x 90 mm (height) x 99 mm (depth) and weighs 0.125 kg. It is ideal for controlling various functions in the packaging, elevator, hoist, textile and water industries. It is compliant with the international standard EN/IEC 60255-1 and certifications such as 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 via the front LEDs and the data can be analyzed using the Harmony NFC app. This saves time and increases efficiency.
