1.2.Models and mounting configurations

Two models of 200I rectifiers are available :

Models NT5C05CA / CB, without an ac cable

Model NT5C05CC, equipped with an ac cable terminated with a male plug

Up to six switch mode 200I rectifiers can be installed in a 23-inch NT6C43CB 1200 A cabinet or in an NT6C40 type frame. The cabinet is specifically designed to provide modularity within a very compact unit. For wooden floor applications in a zone 4 seismic region, up to three rectifiers can be installed in a mounting frame mounting, but they must be installed in the three lowest mounting positions in the frame.
