ABSTRACT:
A motor controller includes an isolation switch having a main power supply terminal and a first bolted pressure contact and a load receptacle having a second bolted pressure contact. The motor controller also includes a drawout unit having a line terminal and a load terminal, the line terminal for engaging the first bolted pressure contact when the drawout unit is in an inserted position and the load terminal for engaging the second bolted pressure contact when the drawout unit is in the inserted position. The drawout unit rests on a drawer which is in turn supported by a pair of sliding rails. A current transformer generates a sensing signal for monitoring purposes. The components are arranged in a compact design which requires significantly less space than conventional designs.
