For general instrumentation, relays, power demand.
         Epoxy-resin-molded wound type.
         Highly compact, excellent insulation reliability.
         In combination with the PD-50HF PT, the CD-40K CT offers compactness, lightness, economy, and simple installation.
         An internal core is employed along with a molded coil.  The core is cut from oriented silicon steel strips, and magnetic characteristics are excellent, in an approach which limits dimensions and weight, Primary terminals are located on the sides and are straight, thereby minimizing connection work.

         40VA from 800/5A up to 400/5A
         Designed for large loads and double ratios, and rated at higher currents than the Type CD-40K can handle.
         Overcurrent capability 75 or 150 times normal, to 600/5A and 300 times to 100/5a.
         With their higher short-circuit capacities, these units are suited to applications where overcurrent strength of 40 times is no longer adequate.
