Vigirex closed toroid for PA differential protection diam 50 mm
- Reference: 50438
This closed toroid is dedicated to Vigilohm insulation fault detection, as well as Vigirex protection and residual current monitoring relays.
The inner diameter of the toroid is 50 millimeters and the weight is 0.200 kg. Cables must be centered in the toroid, and the total diameter of all cables must not exceed 25 millimeters. The maximum cross-section per phase (R, S, T, N) is 50 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 85A.
