With the addition of an extra switch block at the bottom of the basic units, this version of the E7000 Series offers four pole switch capacity with simultaneous timing or two-step timing. The two-step operation is achieved by factory adjust- ment to your specifications. 1216 Catalog 5-1773450-5 Dimensions are shown for Dimensions are in millimeters USA: +1 800 522 6752 For additional support numbers Revised 3-13 reference purposes only. unless otherwise specified.
