Single-phase measuring current transformer for converting up to 100 A primary current to 5 A secondary current in main and sub-distributions. It operates at a maximum operating voltage of up to 1.2 kV and a nominal frequency of 50-60 Hz. It has a rated power of 3 VA and an accuracy class of 1. The CT PRO XT series is suitable for all cables with a diameter of up to 18 mm and busbars up to 20 x 10 mm. A compact housing made of self-extinguishing thermoplastic and flexible mounting options ensure compatibility with common mounting systems (DIN rail, primary conductor, busbar). Optionally, a quick and easy installation can be carried out by connecting the secondary conductor via screw and plug terminals.
