The MA120 closed toroid is specifically engineered for use 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, supporting up to a rated current of 250A for effective monitoring and protection.
With an inner diameter of 120 mm, this toroid has a weight of 0.450 kg. The cables must be properly centered within the toroid, ensuring that their combined outer diameter does not exceed 60 mm. The maximum cross-sectional area per phase (R, S, T, N) for copper conductors is 240 mm², allowing for substantial current handling capabilities.
Operating within a temperature range of -35 to 70 °C, the MA120 is compliant with various environmental standards, including IEC 60947-2. It is designed to withstand exposure to damp heat and salt mist, classified under pollution degree level 3 as per IEC 60664-1. The product features a transformer ratio of 1/1000, making it suitable for various applications in equipment monitoring and control.
