Single-phase measuring current transformer for converting up to 150A primary current to 5A secondary current in main and sub-distribution boards. Operation is possible at a maximum operating voltage of up to 1.2kV and a nominal frequency of 50-60 Hz. It has a nominal power of 5VA and an accuracy class of 1. The CT PRO XT series is suitable for all cables up to a diameter of 18mm and busbars up to 20x10mm. A compact housing made of self-extinguishing thermoplastic and flexible mounting options ensure compatibility with common fastening systems (DIN rail, primary conductor, busbar). A quick and easy installation can be carried out by connecting the secondary conductor via screw and plug-in terminals.
