This toroid is dedicated to Vigilohm Insulation Fault locators, and to VigiPacT type A residual current protection and monitoring relays. It allows the monitoring of the injected component from Vigilohm Insulation Monitor, and the measurement of a current rating up to 630A for VigiPacT monitoring and protection relays. The transformer ratio is 1/1000. The inner diameter of the toroid is 300mm and the weight is 2.280kg. The cables must be centered within the toroid and the diameter represented by all these cables should not exceed 150 millimetres. The maximum cross section per phase (R, S, T, N) is 2 cables of 240mm² for a copper conductor.
- VigiPacT relays ensure coordination with ComPacT circuit breakers (switch off within 40ms)
- Continuous monitoring of the power supply, the relay/toroid link and internal electronics
- Reinforced insulation of VigiPacT relays (overvoltage category IV)
- Access to settings protected by a lead-sealable cover or password
- This product is part of the global Schneider environmental data program
