This PowerTag Energy M250 3P is a wireless communication energy sensor. With its Monoconnect design, it is dedicated to Compact NSX 100/160/250, Compact NS 100/160/250 and TeSys GV5/GV7. It has to be associated with a concentror or a gateway to provide circuit monitoring and diagnosis down to load level. It is designed specifically for Energy Management, Load Monitoring and Power Availability applications. It incorporates accurate real-time measurements of active, and reactive energy, active, reactive and apparent power, current, voltage and power factor. In case of power outage, it sends a voltage loss alarm and the current-per-phase value before being de-energized. PowerTag Energy M250 complies with IEC 61557-12 standard. It is a PMD-II/DD/K70/1. The Performance category is Class 1. The Imax maximum current is 250A. The Ib Base current is 40A. The Saturation current is 500A and the Ist Starting current is 160mA. The Un Rated voltages are Phase-to-neutral 230VAC +/- 20% and Phase-to-phase 400VAC +/- 20%. The maximum consumption is below or equal to 3.7VA. It can be mounted directly on the bottom side of the circuit breaker or Vigi add-on terminals, or top or bottom side of the plug-in base if any. The product color is grey (RAL7016). The weight is 250g. The degree of protection is IP20 and IK07. The operating temperature is between -25°C to +70°C. The storage temperature is between -50°C to +85°C.
