An extensive range of auxiliary switch blocks is available for various applications. The contactors themselves do not have an integrated auxiliary conducting path. One 4-pole or up to four single pole auxiliary switch blocks (with screw or Cage Clamp connections) can be snapped onto the front of the contactors. When the contactors are energized, the NC contacts open before the NO contacts close. The terminal designations of the single-pole auxiliary switch blocks consist of location digits on the basic unit and function digits on the auxiliary switch blocks. In addition, 2-pole auxiliary switch blocks (screw-type terminals) are provided for cable entries from above or below in the style of a four-connector block (feeder auxiliary switch).
