This ring core is designed for the Vigilohm insulation fault location devices and the VigiPacT type A residual current protection and monitoring relays. It enables the monitoring of the supplied component from the Vigilohm Insulation Monitor and measures a rated current of up to 85 A for VigiPacT monitoring and protection relays. The transformation ratio is 1/1000. The inner diameter of the toroid is 50 millimeters, and the weight is 0.200 kg. The cables must be centered within the toroid, and the diameter of all these cables must not exceed 25 mm. The maximum cross-section per phase (R, S, T, N) is 50 mm² for a copper conductor.
