Vigirex – closed toroid – for IA earth leakage protection – diameter 80mm
This closed toroid is dedicated to Vigilohm insulation fault detection, as well as Vigirex protection and residual current monitoring relays.
The toroid has an internal diameter of 80 mm and weighs 0.420 kg. Cables must be centered in the toroid, and the total diameter of all cables must not exceed 40 millimeters. The maximum cross-section per phase (R, S, T, N) is 95 mm² for a copper conductor.
It allows Vigilohm Insulation Monitor to monitor the injected component, and Vigirex monitoring and protection relays to measure nominal currents up to 160A.
