SD-Q DC Interface Contactors

(6/22/2017)

SD-Q DC interface contactors designed to be directly driven by the transistor output DC24V are DC operated contactors of compact size and high ability. By combining the efficient electromagnet with permanent magnet, SD-Q contactors are able to be directly driven by the transistor output DC24V 0.1A of a programmable logic controller, etc. SD-Q series is lineup contained reversing contactors applied to motors of 3ø 440V5.5kW starters with the thermal overload relay, and additional auxiliary contact block, etc.

Features

  • Special design to be directly driven by the transistor output DC24V
  • By combining an electromagnet with permanent magnet, coil operating current is reduced to DC24V55mA(1.3W) for SD-Q11
  • Compliance with many international standards
  • Applicable standards: IEC, DIN, VDE, BS, JIS, JEM
  • Approved standards: UL, CSA, TÜV
  • Built-in surge absorber
  • Provision of terminal covers
  • Mountable on a IEC 35mm width rail
  • Compact size and high performance
    SD-Q11, SD-Q12: 3ø 240V3kW, 3ø 440V4kW
  • Mirror contact: Normally closed auxiliary contact cannot be closed when power contact is welded.
    The function conform to requirements of IEC60947-4-1.
  • Variable combination: Auxiliary contact block (UQ-AX2(KR)) can be added onto a contactor (SD-Q11 (SD-QR11))
