Beyond the breaker function, it packs a full suite of metering: ammeter, voltmeter, wattmeter, frequency meter, and reactive power meter, all with seamless measurement detection. Accuracy runs 0.5 % for current and voltage, 1 % for active power, based on IEC 61557-12, IEC 62053-22, and IEC 62053-23. The status display cycles through voltage, current, active/apparent/reactive power, active energy, line frequency, power factor, temperature, switching cycles, operating hours, trip events, and warnings — all readable on the front face.
Snaps onto a DIN rail (REG fastening), any mounting position. Front face is IP40, rear side IP20 with connected protective device and conductors. Supports a wireless protocol for data communication, though the specific protocol isn't detailed in the base listing. The supply cord position is flexible (any), and the minimum test equipment voltage is 195 V.
