Vigirex closed toroid for differential protection SA diam 200 mm
- Reference: 50441
This closed toroid is dedicated to Vigilohm insulation fault detection and Vigirex residual current monitoring and protection relays.
The inner diameter of the toroid is 200 mm, and the weight is 1.320 kg. Cables must be centered in the toroid, and the total diameter of all these cables must not exceed 100 mm. The maximum cross-section per phase (R, S, T, N) is 2 cables of 185 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 400A.
