Bender LINETRAXX PEM333/330

The universal measuring device PEM330/333 is used to record and indicate electrical quantities
of a public electricity network. The scope of measurements ranges from currents and voltages
through energy consumption and performance to total harmonic distortion and voltage quality
assessment. The active energy measurements are in compliance with the DIN EN 62053-22
class 0.5 S accuracy standard.The current inputs are connected via external …/1 A or …/5 A
measuring current transformers.
