Schneider Electric 50437

This closed toroid is specifically engineered for integration with Vigilohm Insulation Fault locators and VigiPacT type A residual current protection and monitoring relays. It facilitates the monitoring of the injected component from the Vigilohm Insulation Monitor and supports current measurements up to 65 A for effective monitoring and protection.

With a transformer ratio of 1/1000, the toroid has an inner diameter of 30 mm and weighs 0.120 kg. The design mandates that the cables be centered within the toroid, with an overall diameter not exceeding 15 mm for optimal performance. The maximum cross-section allowed per phase (R, S, T, N) is 25 mm² for copper conductors.

Each unit is compatible with multiple VigiPacT residual current protection relays, including models RH10M, RH10P, RH21M, RH21P, RH68M, RH86M, RH86P, RH99M, RH99P, RH197M, RH197P, RHU, RHUs, and RMH, ensuring versatile application across various equipment monitoring and control scenarios.
