Single-phase measuring current transformer for converting up to 50A 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 2VA and an accuracy class of 3. 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). Quick and easy installation can be carried out by connecting the secondary conductor via screw and plug-in terminals. The integrated electronic protection circuit (SELV) also guarantees reliable protection against the risks that can arise from operating a current transformer in idle mode.
