Vigirex closed torus for TA differential protection diam 30 mm
- Reference: 50437
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 30 millimeters and the weight is 0.120 kg. Cables must be centered in the toroid, and the diameter of all cables must not exceed 15 millimeters. The maximum cross-section per phase (R, S, T, N) is 25 mm² for a copper conductor.
It enables Vigilohm Insulation Monitor’s injected component to be monitored, and Vigirex monitoring and protection relays to measure nominal currents up to 65A.
