Closed toroid for residual current protection SA, Ø 200mm. range of product: Vigilohm, Vigirex - device short name: SA200 - product or component type: earth leakage current sensor.

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 400A for VigiPacT monitoring and protection relays. The transformer ratio is 1/1000. The inner diameter of the toroid is 200mm and the weight is 1.320kg. The cables must be centered within the toroid and the diameter represented by all these cables should not exceed 100 millimetres. The maximum cross section per phase (R, S, T, N) is 2 cables of 185mm² for a copper conductor.

• VigiPacT relays ensure coordination with ComPacT circuit breakers (switch off within 40ms)

• Reinforced insulation of VigiPacT relays (overvoltage category IV)
• Access to settings protected by a lead-sealable cover or password
• Green Premium labelled products, RoHS and REACH compliant
• RMS measurement of earth-leakage currents
• No trip under leakage currents below 80% of the threshold
• No trip under transient leakage currents
• Inverse-time tripping curve
