Vigirex – closed toroid – for MA earth leakage protection – diameter 120mm
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 120 mm and weighs 0.450 kg. Cables must be centered in the toroid, and the total diameter of all cables must not exceed 60 millimeters. The maximum cross-section per phase (R, S, T, N) is 240 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 250 A.
