This PowerTag M250 3P is a wirelessly communicating energy meter. With its monoconnect design, it is suitable for ComPact NSX 100-250, ComPact NS 100-250 and TeSys GV5/GV7. It must be connected to a concentrator or a gateway to enable circuit monitoring and diagnostics down to the load level. It is specifically designed for energy management, load monitoring and power availability applications. It includes accurate real-time measurements of active and reactive energy, active, reactive and apparent power, current, voltage and power factor. In the event of a power failure, it sends a voltage loss alarm and the value of the current per phase before de-energizing. The PowerTag Energy M250 complies with the IEC 61557-12 standard and is a PMD-II/DD/K70/1. The power class is Class 1. The maximum current Imax is 250A, the base current Ib is 40A, the saturation current is 500A and the inrush current is 160mA. The nominal voltages are phase-neutral 230VAC +/- 20% and phase-phase 400VAC +/- 20%. The maximum consumption is less than or equal to 3.7VA. It can be mounted directly on the bottom of the circuit breaker, on the Vigi top terminals or on the top or bottom of the connection base (if present). The product color is gray (RAL7016), the weight is 250g and the protection degree is IP20, IK07. The operating temperature is between -25°C and +70°C, the storage temperature is between -50°C and +85°C.
