J7KN

Features

Motor contactors from 4-500kW for normal and heavy-duty switching.

This modular system consists of main contactors and additional contact blocks. The basic units can be combined with auxiliary contacts. AC and DC versions, integrated mechanical interlock, are available as well as 3-main-pole and 4-main-pole versions.

  • Basic units can be combined with auxiliary contacts (top/side mounting)
  • 3-main-pole and 4-main-pole versions are possible
  • The power range covers 4 to 500kW
  • Different coil voltages (AC and DC)
  • J7KN-10D to J7KN-22D models have integrated auxiliary contact for electronic circuits (3-pole versions)
