Schneider Electric 50438 Ø 50 Mm - Closed Toroid for Residual Current Protection Pa

This toroid is dedicated to Vigilohm Insulation Fault locators, and to VigiPacT type A residual current protection and monitoring relays. It allows the monitoring of the injected component from Vigilohm Insulation Monitor, and the measurement of a current rating up to 85A for VigiPacT monitoring and protection relays. The transformer ratio is 1/1000. The inner diameter of the toroid is 50 millimeters and the weight is 0.200kg. The cables must be centered within the toroid and the diameter represented by all these cables should not exceed 25 millimeters. The maximum cross section per phase (R, S, T, N) is 50mm² for a copper conductor.
