The RI-CTS036, 024 Series forms part of a large family of split core single phase moulded case current transformers from Rayleigh Instruments. These transformers are suitable for monitoring current flow in commercial, industrial or utility applications. They are designed to connect any standard metering or relay product requiring a 5A or 1A output and are available with Primary current input ranges of 250A, 300A, 400A and 600A. The RI-CTS036 Series have been designed for ease of installation into existing plants where removal of busbars or cable lugs is impractical. They also have clear markings moulded into the case to indicate the correct direction of primary current flow to minimise installation errors.
