Schneider Electric 50420 Vigirex - tore ouvrant - pour protection différentielle TOA - Ø80mm

This ring core is intended for Vigilohm insulation fault tracing devices and the VigiPacT residual current protection and monitoring relays type A. It allows the monitoring of the fed component of Vigilohm Insulation Monitor and the measurement of a rated current up to 160A for VigiPacT monitoring and protection relays. The transmission ratio is 1/1000. The inner diameter of the toroid is 80 millimeters and the weight is 0.9 kg. The cables must be centered within the toroid, and the diameter of all these cables should not exceed 40 mm. The maximum cross-sectional area per phase (R, S, T, N) is 95mm² for a copper conductor.
