The 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 gateway to enable monitoring of the circuit and diagnostics down to the load level. It has been specifically designed for applications in energy management, load monitoring, and power availability. 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 outage, it sends a voltage loss alarm and the current value per phase before losing power. 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 rated 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 attachment terminals, or on the top or bottom of the connection socket (if available). The product color is gray (RAL7016), the weight is 250g, and the protection class is IP20, IK07. The operating temperature ranges from -25°C to +70°C, while the storage temperature ranges from -50°C to +85°C.
