Single-phase measuring current transformer for converting up to 400A 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 0.5. The CT MAX series is used in distribution boards with 30x15 mm and 40x10 mm busbars. 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 using screw and plug-in terminals.
